Developed by Microsoft, Outlook is a popular email client that helps us manage our mails from multiple sources under one roof. Since Outlook has so many advantages, a lot of people use it as their default mail client on Mac as well. While it runs smoothly most of the time, users seldom face unwanted problems with us. For instance, we often get complaints like Outlook not working or the Outlook calendar is not syncing. It doesn't matter what kind of Outlook issue on Mac you are facing with, we are here with all kinds of easy and working solutions in this guide.
Part 1. Outlook Not Opening on Mac?
This is one of the most commonly faced Outlook related issues with Mac. Chances are that even after some attempts, Outlook might not open or launch on your system. This can happen due to a firmware issue with Mac or the Outlook application. Here are some of the simple ways to fix Outlook not opening on Mac.
Solution 1: Restart Mac
If Mac is blocking Outlook from opening, then a simple restart would be able to fix it. This will reset its present power cycle and cache automatically, fixing app-related issues with it.
- Just go to the Finder and click on the Apple logo on the top.
- From here, you can restart your Mac without any trouble.
- Try launching Outlook again after it restarts.
Solution 2: Run Outlook without Connectivity
Sometimes, while launching the app, a connectivity-related process can make Outlook not working. For instance, it can keep checking the scheduled emails or sending/receiving some attachments in the background.
- Just press and hold the Shift key on your Mac and launch Outlook.
- Once it is opened successfully, close it, and relaunch it in the normal mode.
Solution 3: Verify Outlook Identity
If you are working with an older version of Office 2011, then it can cause some clash with Outlook Identities. Here's how you can fix Microsoft Outlook not opening by verifying Office identity.
- Launch Finder on Mac and go to Documents > Microsoft User Data > Office 2011 Identities.
- Copy the Identity folder from here and drag it to the desktop.
- Try launching Outlook on Mac again.
Part 2. Outlook Not Connecting on Mac?
There are times when even after launching Outlook, it fails to connect to the web. This stops all the prominent features of the app and doesn't allow us to send or receive mails. The good news is that the Outlook not connecting issue can easily be fixed.
Solution 1: Check the network connection
Before you take any drastic measure, make sure that your Mac is connected to a stable internet connection. You can try to open any other website on a browser to check the connectivity.
Solution 2: Check Outlook Connectivity Status
One of the best things about Outlook is that it lets us work offline. Therefore, if the connection is turned off, then you might feel that Outlook is not working on Mac.
- Firstly, launch Outlook on your Mac and go to its Tools section.
- Here, you can check the status of connectivity. If it is turned off, then simply enable it.
- You can click on the 'Sync Error' prompt to further view and diagnose any connectivity issue on Mac.
Solution 3: Reset your Account
If your Mac and Outlook are both connected to a stable network, and you still get this issue, then consider resetting your account. To do this, you need to delete your account from Outlook and later add it again.
- Open Outlook and go to its Tools > Accounts.
- Go to the Account Settings and select the account you wish to remove.
- Click on the 'Delete' button and confirm your choice to remove the account.
- Launch Outlook again and add the account details to reset it.
Part 3. Outlook Not Responding on Mac?
Is Outlook not responding on Mac and has been stuck? It might surprise you, but a lot of people also encounter this situation. The application often gets stuck and doesn't respond to any command on Mac. The best solution to this is simply closing the application on Mac and starting it again.
Solution 1: Forcefully quit Outlook
Since Mac allows us to close the apps that are not responding, you can easily quit Outlook as well. Here's how you can fix Outlook not responding issue on Mac.
- Simply go to the Finder and click on the 'Force Quit Applications' button. Also, you can press the Command + Option + Esc keys at the same time.
- As the Force Quit Applications window will open, you can view the apps running in the background. Select Outlook from here and close it on your Mac.
- Wait for a few seconds and launch Outlook again.
Solution 2: Boot Mac in Safe Mode
In case if there is an issue with Mac's network or security component that is making Outlook not working, then you should boot it in the safe mode instead.
- Restart your Mac or turn it on, if it isn't already.
- Press and hold the Shift key for a few seconds and release it once Mac boots in the safe mode.
- Log-in to the respective user account and launch Outlook in the safe mode.
Part 4. Outlook Not Updating on Mac?
While working with Outlook, you might encounter that the app has stopped updating the inbox. You can also get the Outlook not updating issue with the entire app or merely a linked account. There are a few solutions that you can try to fix the update issue with Outlook.
1. Outlook Not Updating
If the entire app (including all the folders and accounts) has stopped updating, then you should try to repair or reset the app.
Solution 1: Go Offline/Online
Although Outlook allows us to work offline, sometimes it can leave the app in an inactive state.
- Launch the application and go to Finder > Outlook.
- Enable the Work Offline feature and close the application.
- Open the app again after a while and disable the 'Work Offline' feature.
Solution 2: Run Outlook Diagnostics
This is something that even the regular users of Outlook are not aware of. Just like every other leading Microsoft app, Outlook can also repair itself. All you need to do is run the diagnostics to fix the Outlook not updating issue.
- Start by launching Outlook on Mac and go to its Menu > Info > Account. In older versions, it is listed under Tools > Account.
- From here, you need to open the Outlook Account Settings.
- Go to the Email section and click on the 'Repair' button. Now, follow simple on-screen instructions to run the diagnostics.
2. Outlook Inbox Not Updating
Apart from that, chances are that your Outlook inbox might encounter some syncing issues as well. Here are some simple fixes for the Outlook inbox not updating problem.
Solution 1: Empty mail cache
If there is a problem specific to your inbox, then you can fix it by clearing its cache. This will only erase some temporary files and won't tamper with your overall Outlook experience.
- Launch Outlook on Mac and select your Inbox from the sidebar.
- Right-click to get its context menu and visit its Properties.
- Go to the 'General' tab of Inbox Properties and click on the 'Empty Cache' button.
- Confirm your choice by clicking on the 'Empty' button again.
Solution 2: Run Outlook Diagnostics
Unlike Windows that stores OST files for Outlook, Mac stores each data record separately. This is why multiple records can sometimes cause an unwanted clash in the system. If your Microsoft Outlook not responding, then consider deleting the unwanted records from Mac.
Outlook For Mac Not Working
- Close Outlook and go to Finder on your Mac.

Solution 1: Empty Calendar Cache
This will not delete all the cache data on your Outlook, but would reset the calendar cache. Once it is done, restart the app to fix Outlook calendar not syncing.

- Go to the General section and click on the 'Empty Cache' button to remove the cache content related to Calendar.

When you open a file or send an email message in Microsoft Outlook 2010 or later versions, Outlook freezes, or you receive the following error message:
Outlook not responding
This problem occurs for one or more of the following reasons:
- You have not installed the latest updates.
- Outlook is in use by another process.
- Outlook is loading external content, such as images in an email message.
- A previously installed add-in is interfering with Outlook.
- Your mailboxes are too large.
- Your AppData folder is redirected to a network location.
- You have to repair your Office programs.
- Outlook data files have become corrupted or damaged.
- Your installed antivirus software is outdated, or it conflicts with Outlook.
- Your user profile has become corrupted.
- Another program conflicts with Outlook.
- This issue may occur for one or more of the reasons in this section. To fix this issue, you may have to follow the troubleshooting steps in the Resolution section.
- Many of these items can be automatically checked by the Microsoft Support and Recovery Assistant (SaRA). To start the automated checks, follow these steps:
- Install the Outlook Advanced Diagnostics tool.
- Select Run when you are prompted by your browser.
- In the report that's generated, review the items on the Issues found tab. For configuration details about Outlook, Windows, and you computer, review the settings on the Detailed View tab.
To resolve this problem, make sure that your computer meets the Outlook 2016 system requirements, Outlook 2013 system requirements or Outlook 2010 system requirements.
These steps are provided in a specific order based on commonality and complexity. Follow these steps in the given order.
Step 1 - Install the latest updates
The Office installation on your computer might not be up to date. This might be because Windows Update is not configured on your computer to automatically download and install recommended updates. By installing important, recommended, and optional updates, you can often correct problems by replacing out-of-date files and fixing vulnerabilities. To install the latest Office updates, click the link for your version of Windows, and then follow the steps in the article:
Make sure that the latest updates for Outlook are installed. For more information, see How to install the latest applicable updates for Microsoft Outlook (US English only).
Step 2 - Make sure that Outlook is not in use by another process
Performance may be decreased if you use the Outlook AutoArchive feature or sync to Outlook with a mobile device. This is because these processes can use a large number of resources.
If Outlook is in use by another process, this information is displayed in the status bar at the bottom of the screen. If you try to perform other actions while Outlook is in use, Outlook may not respond. Let the task in process finish its job before you try another action.
Step 3 - Check the problem that caused by external contents
To resolve this issue, use one of the following methods:
- Prevent Outlook to download external contents. To do this, go to File > Options > Trust Center > Automatic Download, select the following two options:
- Don't download pictures or other content automatically in HTML e-mail option.
- Warn me before downloading content when editing, forwarding, or replying e-mail.
- Avoid sending such an email with external source.
Step 4 - Investigate possible add-in issues
Although add-ins can enhance your user experience, they can occasionally interfere or conflict with Outlook. Try to start Outlook without any add-ins running.
How to start Outlook without add-ins
- Do the following, as appropriate for your operating system:
- If you are running Windows 8, swipe in from the right edge of the screen, and then tap Search. (If you are using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then select Search.) Type Run in the search box, and then tap or select Run.
- If you are running Windows 10, Windows 7 or Windows Vista, select Start.
- If you are running Windows XP, select Start, and then select Run.
- Type Outlook.exe /safe, and then select OK.
- If the problem is resolved, select Options on the File menu, and then select Add-Ins.
- Select COM Add-ins, and then select Go.
- Clear all the check boxes in the list, and then select OK.
- Restart Outlook.
If the problem does not occur after you restart Outlook, one of the add-ins is likely the cause of the problem. Restore the add-ins one at a time until the problem does occur to determine which add-in is causing the problem.
Step 5 - Check whether your mailbox is too large
As your mailbox size increases, more resources are required to open each folder. If you have a large number of items in any single folder, you may experience performance issues during certain operations. For more information, see Outlook performance issues when there are too many items or folders in a cached mode .ost or .pst file.
We recommend that you move several items in your larger folders to separate folders, or that you archive those items by using the AutoArchive feature.
How to create a folder
On the Folder tab, select New Folder in the New group.
In the Name box, enter a name for the folder.
In the Select where to place the folder list, select the location for the new folder.
The new folder will become a subfolder of the folder you select.
To manage your mailbox by reducing the size of the Outlook data file, see Reduce the size of Outlook Data Files (.pst and .ost).
To manage your mailbox by using the AutoArchive feature, see AutoArchive settings explained.
Step 6 - Check whether your AppData folder is being redirected to a network location
Outlook stores certain data, such as email signatures and the spelling checker dictionary, in the AppData folder. If the network is performing slowly, Outlook must wait for read and write operations to the AppData directory to finish.
How to disable redirection of the AppData directory
Start Registry Editor. To do this, use one of the following procedures, as appropriate for your version of Windows:
- Windows 10 or Windows 8: Press Windows Key+R to open a Run dialog box. Type regedit.exe and then press OK.
- Windows 7: Select Start, type regedit.exe in the search box, and then press Enter.
In Registry Editor, locate and then select the following subkey:
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell Folders
Locate and then double-click the AppData value.
In the Value data box, type the following path, and then select OK:
Exit Registry Editor.
Step 7 - Repair Office programs
You can automatically repair your Office program files to resolve such problems as Outlook freezing or not responding.
How to automatically repair Office
- Exit any Microsoft Office programs that are running.
- Open Control Panel, and then open the Add or Remove Programs item (if you are running Windows XP) or Programs and Features (if you are running Windows 10, Windows 8, Windows 7, or Windows Vista).
- In the list of installed programs, right-click Microsoft Office 2016, Microsoft Office 2013 or Microsoft Office 2010, and then select Repair.
Step 8 - Repair Outlook data files
When you install Outlook, an Inbox repair tool (scanpst.exe) is also installed on your PC. The Inbox repair tool can resolve problems by scanning your Outlook data files, and repairing errors. To use the Inbox repair tool, exit Outlook, and then follow the steps in Repair Outlook Data Files (.pst and .ost).
Step 9 - Check whether antivirus software is up-to-date or conflicts with Outlook
If your antivirus software is not up-to-date, Outlook may not function correctly.
How to check whether antivirus software is up to date
To keep up with new viruses as they are created, antivirus software vendors periodically provide updates that you can download from the Internet. Download the latest updates by visiting your antivirus software vendor's website.
For a list of antivirus software vendors, see Consumer antivirus software providers for Windows.
How to check whether antivirus software conflicts with Outlook
If your antivirus software includes integration with Outlook, you may experience performance issues. You can disable all Outlook integration within the antivirus software. Or, you can disable any antivirus software add-ins that are installed in Outlook.
When you change your antivirus settings, this may make your PC vulnerable to viral, fraudulent, or malicious attacks. We do not recommend that you try to change your antivirus settings. Use this workaround at your own risk.
You may have to contact your antivirus software vendor to determine how to configure the software to exclude any integration with Outlook or to exclude scanning in Outlook.
If you also plan to perform file-level virus scanning of .pst, .ost, Offline Address Book (.oab), or other Outlook files while Outlook is in use, see Plan antivirus scanning for Outlook 2010 or Planning considerations for deploying Outlook 2016 for Windows.
Step 10 - Create a user profile in Outlook
To create a user profile, follow these steps:
In Control Panel, select Programs, select User Accounts, and then select Mail to open Mail items.
Select Show Profiles.
Select the profile that you want to remove, and then select Remove.
In the Profile Name dialog box, type a name for the profile.
Specify the user name, the primary SMTP address, and the password. Then, select Next.
You may receive the following prompt:
Allow this website to configure <[email protected] server> settings?
In this prompt, select the Don't ask me about this again checkbox, and then select Allow.
Step 11 - Perform a Selective Startup (advanced users)
When you start Windows normally, several applications and services start automatically and then run in the background. These applications and services can interfere with Outlook. A Selective Startup or 'clean boot' process can help you identify problems that are caused by application conflicts.
If you use the Selective Startup option in System Configuration, you can turn services and startup programs on or off individually to check whether the problem occurs the next time that you start your computer. In System Configuration, if you select a check box, the related service or startup program runs when you restart the computer. If the check box is cleared, the service or startup program does not run when you restart the computer.
Follow this procedure to use the process of elimination to identify the problem in Windows 10, Windows 8, Windows 7, or Windows Vista.
For more information about performing a clean boot, see How to perform a clean boot in Windows.
How to do a Selective startup
In Control Panel, select System and Security, select Administrative Tools, and then double-click System Configuration.
If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.
Select the General tab, select Selective startup, and then clear the Load system services and the Load startup items check boxes.
Select the Load system services check box, select OK, and then select Restart.
If the problem reoccurs after you restart the computer, do one or both of the following tasks, as necessary.
To determine which system service is causing the problem
In System Configuration, select the Services tab, select Disable all, select the check box for the first service that is listed, and then restart the computer.
If the problem doesn't reoccur, then you can eliminate the first service as the cause of the problem.
With the first service selected, select the second service check box, and then restart the computer.
Repeat this process until you reproduce the problem.
If you can't reproduce the problem, you can eliminate system services as the cause of the problem.
To determine which startup item is causing the problem
In System Configuration, select the General tab, and then select the Load startup items check box.
Select the Startup tab, select Disable all, select the check box for the first startup item that is listed, and then restart the computer.
If the problem doesn't reoccur, you can eliminate the first startup item as the cause of the problem.
While the first startup item is selected, select the second startup item check box, and then restart the computer. Repeat this process until you reproduce the problem.
Step 12 - Create a Windows user profile (advanced users)
Your user profile is a collection of settings that let you customize the computer appearance and performance. It contains settings for desktop backgrounds, screen savers, sound settings, and other features. User profiles help make sure that your personal preferences are used when you log on to Windows.
To determine whether this problem is caused by a corrupted user profile, create a user profile to see whether the problem still occurs when you use the new profile.
How to repair a corrupted user profile in Windows 8
Step 1 - Create a user account
To create a user profile, you must first create a user account. When the new account is created, a profile is also created.
Swipe in from the right edge of the screen, and then tap Search. (If you are using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then select Search.) Type Command Prompt in the search box, right-click Command Prompt, and then select Run as administrator.
If you're prompted for an administrator password or for confirmation, type the password or provide confirmation.
Type net user UsernamePassword /add, and then press Enter.
Step 2 - Copy old files to the new user profile** After you create the profile, you can copy the files from the existing profile
You must have at least three user accounts on the computer to complete these steps. This includes the new account you just created.
Log on as a user other than the user that you just created or the user that you want to copy files from.
In Control Panel, select Appearance and Personalization, and then select Folder Options.
Select the View tab, and then select Show hidden files, folders, and drives.
Clear the Hide protected operating system files check box, select Yes to confirm, and then select OK.
Open File Explorer. To do this, Swipe in from the right edge of the screen, and then tap Search. (If you are using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then select Search.) Enter File Explorer in the search box, tap or select Apps, and then tap or select File Explorer. Type Command Prompt in the search box, right-click Command Prompt, and then select Run as administrator.
Locate the C:UsersOld_Username folder, in which C is the drive that Windows is installed on, and Old_Username is the name of the profile that you want to copy files from.
Select all the files and folders in this folder, except the following files:
On the Edit menu, select Copy.
Locate the C:UsersNew_Username folder, in which C is the drive that Windows is installed on, and New_Username is the name of the user profile that you created earlier in this method.
On the Edit menu, select Paste.
Log off, and then log back on as the new user.
Outlook For Mac Not Starting
If you have email messages in an email program, you must import your email messages and addresses to the new user profile before you delete the old profile. If everything is working correctly, you can now delete the old profile.
