Office Add-ins prevented by 365

Hi Eleanor,

Based on your issue description, the error message indicates that Office Store Add-ins might be blocked by the Administrator. Hence, when the user tends to use add-ins on Office App. It would show the message as below.

User can double check with the administrator for the setting. Go to Office365 portal> Admin > Settings > Service & add-ins > User owned apps and services > Ensure “Let users access the Office Store”

If the administrator has confirmed the option is on for all users. Please try following methods and see results:

1: Update to the latest Office version. Certain unexpected issue might be occurred when you are using an old version client.

2: Enter Mac Safe Mode, the issue could be happened due to other programs crash, such  as Front Manager.

3: Delete Office cache files. Some issues may be caused by the cache files as well.

• Go to Finder > Press COMMAND +Shift+g
• In the window pops up, enter “ ~/Library ” and click Go
• Go to Containers folder and delete following folders to Trash
  • com.microsoft.errorreporting
  • com.microsoft.Excel
  • com.microsoft.netlib.shipassertprocess
  • com.microsoft.Office365ServiceV2
  • com.microsoft.Outlook
  • com.microsoft.Powerpoint
  • com.microsoft.RMS-XPCService
  • com.microsoft.Word
  • com.microsoft.onenote.mac

Notes: Outlook Data will be removed when you delete these folders. Please backup before remove.

4: Try to create a new user profile on Mac to make sure the issue isn’t related to Mac profile corruption.

After you have tried these methods and the issue still exists. Please provide following information to us:

1: What is your Office for Mac version and MacOS version you are using? You can open an Office App, such as Word > Choose Word > Select About Word.

2: Does the same issue occur to all Office Apps on user’s Mac or just one Office App only?

Best regards,
