Cannot uninstall Outlook add-in in Outlook desktop app

Question

Hi,

One user of our Outlook add-in reported to us that he can't uninstall the add-in in Outlook desktop app. After trying uninstall the add-in many times, even reinstalled Outlook app, the add-in is still there! The user also tried uninstall it in the web app, it's successful, but in the desktop the add-in is always there.

The user is on Windows 10, Outlook desktop app version number is version 2110 build 16.0.14527.20270. But we can't reproduce this issue.

Did anyone ever experience such an issue? Is there something like a cache needed to be purged? Please Advice.

Thanks in advance!

Hi @Zhanming Cao ,
How did you uninstall Outlook add-in?
Based on my test, there are mainly two methods to remove the add-in from Outlook.

1. File > Options > Add-Ins > Manage COM Add-ins > Go... > Select the add-in you want to remove > Remove button.

2. Get Add-ins >My add-ins > Remove

The user is on Windows 10, Outlook desktop app version number is version 2110 build 16.0.14527.20270

According to my search, the version you mentioned is not the latest. Please upgrade to the latest via File > Office Account > Update Options >Update now.
If above doesn’t help, it is recommend to create a new profile and add the account and see if the issue continues.
(1)Exit Outlook.
(2)In Control Panel, click Mail.
(3)Choose Show Profiles > Add. In the Profile Name box, type a name for the profile, and then choose OK.
(4)Add the account.
