Frequently Asked Questions
Why does Microsoft Office take up so much space in my Mac's 'Other' storage?
Microsoft Office apps frequently generate log files, cache data, and application support files to improve performance. Over time, these temporary files, combined with downloaded Outlook attachments, accumulate and take up significant space under the 'Other' category in macOS storage.
Will deleting Microsoft cache folders from Library remove my actual documents?
No. Deleting the cache folders for Word and Excel located in '~/Library/Containers' will only remove temporary application data and preferences. Your actual saved documents (.docx, .xlsx) remain safe. However, deleting the Outlook folder will delete your downloaded emails.
How can I safely back up my Outlook data on Mac before clearing storage?
To back up Outlook data, open Microsoft Outlook, click 'File' > 'Export', select the items you want to back up (Mail, Calendar, Contacts), and save the generated .olm file to an external drive or cloud storage.
Why are my Outlook calendar entries missing after trying to clear cache files?
If you inadvertently deleted or altered the Outlook container folder in the Library, the local database containing your calendar and mail data may have been reset. If your account is an Exchange or Outlook.com account, resyncing should restore the data; otherwise, you must restore it from a backup.
