Solution 1Recommended

Delete and Recreate the Microsoft Registration Database

Corrupted recent and pinned file databases can cause this error. Resetting this file forces Office to rebuild the list.

The registration database file tracks the locations of your recent and pinned files. Deleting it will safely prompt Microsoft Office to generate a fresh, uncorrupted file upon its next startup.

1
Quit Office Applications

Completely quit all open Microsoft Office applications, including Word, Excel, and PowerPoint.

2
Open Go to Folder

Open Finder, click 'Go' in the top menu bar, and select 'Go to Folder', or press Command + Shift + G on your keyboard.

3
Navigate to the Group Containers Folder

Type the path `~/Library/Group Containers/UBF8T346G9.Office` and press Return.

4
Delete the Database File

Locate the file named `MicrosoftRegistrationDB.reg` and move it to the Trash.

5
Restart Office

Relaunch Word or Excel. The application will recreate the database file and begin accurately tracking your recent files again.

Delete and Recreate the Microsoft Registration Database

Frequently Asked Questions

Why do my recent files show 'file not found' in Office for Mac?

This usually happens when the Office registration database or secure bookmarks preference file becomes corrupted, often after a software update. The application loses the correct path to the file, even if the file itself still exists on your Mac.

Will deleting MicrosoftRegistrationDB.reg delete my actual documents?

No. Deleting this file only resets the database that tracks your recent and pinned file history. Your actual documents, spreadsheets, and presentations remain completely safe in their original folders.

How can I open my files if the recent list is broken?

You can bypass the broken recent list by locating the file directly in Finder and double-clicking it, or by using the 'File' > 'Open' menu within Word or Excel to manually navigate to the file's location on your hard drive.

Does signing in and out of my Microsoft account fix this issue?

Signing in and out primarily affects files synced via OneDrive or SharePoint. If the issue involves local files on your Mac, resetting the local registration database or secure bookmarks preference files is the correct solution.
