How to Fix Missing Undo Edit and Insert Citation Notifications in Word for Mac
Product
Microsoft Word for Mac
Device & OS
macOS
Scenario
Editing a document with third-party macros or citation add-ins (such as Zotero) installed.

Solution 1Recommended

Remove Conflicting Add-ins from Word's Startup Folder

Since Word does not natively use these specific buttons, removing the conflicting add-in (like Zotero) from the Startup folder stops the erroneous notifications.

Third-party citation tools like Zotero use macro files (.dotm) that load automatically when Word starts. If these files become corrupted or incompatible after an update, they trigger missing button notifications.

1
Quit Microsoft Word

Right-click the Microsoft Word icon in your Mac dock and select 'Quit' to ensure the application is completely closed.

2
Navigate to the Word Startup folder

Open Finder. Press Command + Shift + G to open the 'Go to Folder' window. Type in '~/Library/Group Containers/UBF8T346G9.Office/User Content/Startup/Word/' and press Return.

3
Remove the Zotero Add-in

Locate the file named 'Zotero.dotm' (or any other recently installed add-in file). Drag this file to the Trash to remove it from the startup sequence.

4
Restart Word

Launch Microsoft Word again and open a document. Type and click around to verify that the notifications have stopped.

Contact Support if Needed: If you rely heavily on Zotero for citations, try downloading the latest version of the Zotero Word plugin from their official website or contact Zotero Support for a permanent fix.

Frequently Asked Questions

Why does Word say 'Undo Edit' or 'Insert Citation' is missing?

Microsoft Word does not natively feature buttons with these exact names. These notifications are usually triggered by a malfunctioning third-party macro or citation add-in, such as Zotero, attempting to execute commands that aren't recognized by your current version of Word.

Will removing Zotero from the startup folder delete my saved citations?

No. Removing the 'Zotero.dotm' file from Word's Startup folder only disables the integration toolbar within Microsoft Word. Your actual citation library and research data remain safely stored within the standalone Zotero application.

How do I find out which add-in is causing the error if I don't use Zotero?

You can isolate the problem by starting Word in Safe Mode (hold the Shift key while opening Word). If the errors stop, go to 'Tools' > 'Templates and Add-ins' from the top menu, and disable your add-ins one by one until you find the one causing the notifications.
