Has anyone found a reliable fix for the Teams Meeting add-in for Outlook disappearing after a Teams update?

We’re seeing this happen quite often after Teams updates, the add-in is no longer available in Outlook. Users can’t re-add it themselves because it requires admin privileges, so we end up reinstalling it manually for each user, which obviously doesn’t scale.
Has anyone else run into this? If so, how did you solve it?

Team Meeting Addin is installed as user admin. And enabling COM Addins in Outlook also doesn't require Admin rights. So not sure what you are talking about there.
Also for us it was just not being loaded not disappearing. All we did was set a registry key to force load the addin and had no problems since.

I've seen the addin disappear in my environment, but it hasn't been an issue for quite a while, can't say if a GPO was deployed to resolve it or not.

Had this a lot with 2021/2024 LTSC. Moved over to 365 Apps for Enterprise and haven't experienced it since.

We put in a fix for this like two or so years ago, there is a reg key that prevents addins from being disabled due to performance. At point it was listed as a known issue for the addin somewhere, very well could be still, but who knows.

Close outlook, log out of teams, log back in, open outlook.

Yes. The teams login seems to trigger the install.

Not sure if this is related; I had to disable to Avast Outlook plugin for some users as it was actively disabling the Teams add-in. There was no related setting in Avast so I ended up removing it from the registry.
