Safely Rename or Move the Folder for Troubleshooting

Instead of permanently deleting the folder, renaming it allows Office to create a fresh folder while keeping your old data safe for restoration if needed.

This is the safest method if you are trying to fix application crashes or reset your settings. By renaming the folder, Office will act as if it's running for the first time and automatically generate a new user data directory.

Close All Office Apps

Quit all running Microsoft Office applications, including Word, Excel, PowerPoint, and Outlook. Make sure they are not running in the background.

Locate the Folder

Open Finder, navigate to your 'Documents' folder, and look for the folder named 'Microsoft User Data'.

Rename the Folder

Right-click the folder, select 'Rename', and change its name to 'Microsoft User Data_OLD' or 'Microsoft User Data_Backup'.

Restart Office

Launch Microsoft Word or Outlook. The application will automatically generate a fresh, default Microsoft User Data folder.

Safely Rename or Move the Folder for Troubleshooting

Outlook Data Warning: If you use an older version of Outlook for Mac, renaming this folder will hide your current emails, contacts, and profiles. Only do this if you know your emails are synced to the cloud or you are intentionally resetting your profile.

Solution 2

Back Up and Delete the Folder

If you no longer use Microsoft Office or desperately need disk space, you can delete the folder after securing a backup on an external drive.

Frequently Asked Questions

What exactly is stored in the Microsoft User Data folder on my Mac?

This folder typically contains Microsoft Office preferences, custom dictionaries, saved email signatures, custom templates, and, for older versions of Office (like Office 2011), your entire Outlook email database and account settings.

Will deleting this folder uninstall Microsoft Office applications?

No, deleting the Microsoft User Data folder will not uninstall applications like Word, Excel, or Outlook. It only removes your personalized settings, user configurations, and local email data.

How can I restore my Outlook data if I accidentally deleted the folder?

If you simply moved it to the Trash, you can open the Trash, right-click the folder, and select 'Put Back'. If you have already emptied the Trash, you will need to restore the folder from a Time Machine backup or another external backup drive.

Can I permanently move the Microsoft User Data folder to an external drive to save space?

While you can back it up to an external drive, Microsoft Office requires this folder to remain in your local Documents directory to function properly. Moving it permanently may break functionality in apps like Outlook unless advanced symlinks are used.
