It seems some of our users are getting updated to a new release and they can no longer access the Outlook Add-In

Hi @SETJH
Can you please check if after the updates by any chance the Add-In is in Disabled State. In case yes then try to Enable the same from the Outlook using the following steps.
1. Open Outlook > Options > Add-in > Last Option Manage > Drop Down > Disable Add-In > Check if Microsoft Teams Add-in for Office is in disabled state.
Try Enabling the same and restart Outlook and Teams Application and see if this fixes the issue.
With Regards,

We ran into this issue and the addin was completely unregistered. It appeared to happen during a failed update to the addin.
We were able to resolve it by manually registering the addin using the following script which has to be run in command prompt since powershell will not work.
C:\WINDOWS\system32\regsvr32.exe /n /i:user "%LOCALAPPDATA%\Microsoft\TeamsMeetingAddin\1.0.20031.2\x64\Microsoft.Teams.AddinLoader.dll"
In our environment we have both 32bit and 64bit office installs and only the 64bit installs would reregister the addin DLL but the 32bit ones failed.
Already had a case open but the answers provided were not helpful or resolve the issue.

Kindly explain your environment. Is affected user a Mac user or Windows user. Where is the user mailbox hosted (fully online or homed on-prem), with (Microsoft or a third party) mail providers.

That only works if the registry entry AND the DLL are present. Microsoft won't direct you to the DLL.
The registry entry is easy to build but without the DLL you are hosed. The only thing i can think of is to boot up a computer that has been offline for a month, not connect it to internet and grab the DLL and xfer to a flash drive. Unless you have another work around for me?
