Question

some apps have encountered errors when trying to update on Mac

Answer 1

Please Do Not do as the AI bot suggested. It most likely is not necessary, may cause loss of any customizations & probably will not resolve the issue. AI is artificial intelligence, it is neither wisdom nor experience.

When you attempt to update click the expander button

in the Microsoft AutoUpdate [MAU] dialog window to determine exactly which apps are being referred to. Include a listing of the exact names or a screenshot in your reply. The files most likely are remnants from an earlier version of Mac Office. If so, they can simply be deleted once you confirm what they are.

Also, please provide the present Version Number of both Mac Office & macOS... It's always a good idea to include that info when submitting a question.

For Mac update errors where some Microsoft 365 apps (such as Word, Excel, PowerPoint, Teams) will not update while others do, the supported resolutions in similar cases are:

1. Try a full reinstall of Microsoft 365 for Mac
   • Quit all Office apps.
   • In Finder, open Applications.
   • Select all Microsoft 365 apps (Word, Excel, PowerPoint, Outlook, OneNote, Teams if present) and move them to Trash.
   • Empty Trash if desired.
   • Reinstall Microsoft 365 apps by signing in to the Microsoft account and downloading the Mac installers again.
   • This approach resolved “cannot install update” and “error updates” for Word/Teams/PowerPoint in a similar macOS scenario.
2. If apps still will not start or update after reinstall
   • Quit all Office apps.
   • In Finder, select Go → Go to Folder… and open:
     • ~/Library/Containers/
   • Delete the folders starting with:
     • com.microsoft.Word
     • com.microsoft.Excel
     • com.microsoft.Powerpoint
     • com.microsoft.Outlook
     • com.microsoft.OneNote
   • Go back to ~/Library and open Group Containers.
   • Move these (if present) to Trash:
     • UBF8T346G9.ms
     • UBF8T346G9.Office
   • Then reinstall the Office apps again from the Microsoft account portal.
3. If the update error is specifically for “Microsoft Error Reporting 2.2”
   • Open Microsoft AutoUpdate.
   • Right‑click the icon next to Microsoft Error Reporting 2.2 and choose Show in Finder.
   • In Finder, this opens /Library/Application Support/Microsoft/MERP2.0.
   • Delete the MERP2.0 folder.
   • Or navigate manually in Finder to /Library/Application Support/Microsoft/ and delete MERP2.0.
   • Run Microsoft AutoUpdate again.
4. If updates still fail after all of the above
   • Completely uninstall and reinstall Microsoft 365 again after any major macOS update, as this has resolved persistent 500.30/launch/update issues for some users.

These steps are non-destructive to documents but do remove Office app settings and may require signing back in.
