Outlook 2019 Undo Doesn't Work

Question

I'm running Windows 10 (Edition Windows 10 Home Version 21H1 Installed on ‎11/‎21/‎2021 OS build 19043.1348 with Experience Windows Feature Experience Pack 120.2212.3920.0) with Outlook 2019 MSO (16.0.13127.20566) 64 bit. The Undo button doesn't work! So, for example, I'm looking at my Inbox and decide a particular mail is of no interest to me so I delete it. But then I decide I really do want to read it and I immediately click the Undo button. The mail never returns to my Inbox. Anyone know how to fix this?

Hi @Ratterman ,
From your description, does the issue occur after installing Outlook2019?
Have you tried using Ctrl + Z instead of the Undo button?
All the undo operations failed or only undo delete failed?

According to my search, there are several reasons for the issue, and you can try the following troubleshooting:

1. Try removing the undo button from Quick Access Bar and then re-add it.
   (1)Right-click the undo button and select Remove from Quick Access Toolbar
   
   (2)Re-add Undo again.
   
2. Verify if the issue is related to any third-party add-ins, please try starting Outlook in safe mode and test it again.
   (1)Close Outlook
   (2)Choose Start>Run
   (3)In the Open box, type outlook.exe /safe
   If the issue continues, you may try to Repair Office from the Control Panel and see if it works.
