Method 2: 

Reregister the Teams Add-in DLL File

The “Microsoft.Teams.AddinLoader.dll” file helps the Teams Meeting add-in work smoothly in Outlook. Re-registering this Dynamic Link Library (DLL) file can restore the Teams Meeting add-in to your Outlook application.

It’s a lengthy but straightforward process. Close Microsoft Teams and Outlook and follow the steps below to re-register the “Microsoft.Teams.AddinLoader.dll” file.

1. First, you need the path/location of the Microsoft.Teams.AddinLoader.dll file on your PC. Open the File Explorer (Windows key + E), select View on the top menu, choose Show, and select Hidden items.

2. Open C:\Users\Username\AppData\Local\Microsoft\TeamsMeetingAddin\1.0.23241.2\x64
3. Open the x86 folder if you have a 32-bit PC or the x64 folder if your PC is 64-bit. See 4 Ways To Tell If You’re Using 32-Bit Or 64-Bit Windows.

4. You should find the “Microsoft.Teams.AddinLoader.dll” file in this folder. Copy the file path in the File Explorer’s address bar.
5. Open the Start menu, type cmd in the search box, and select Run as administrator below the Command Prompt app.
   
   
6. Type cd, press the Spacebar, paste the Microsoft.Teams.AddinLoader.dll file path (see step #7) and press Enter. The command should look like the one below.cd C:\Users\username\AppData\Local\Microsoft\TeamsMeetingAddin\1.0.23034.3\x64

       7.    Next, paste regsvr32 Microsoft.Teams.AddinLoader.dll on the following line and press Enter.

 

7.       You should see a “DllRegisterServer in Microsoft.Teams.AddinLoader.dll succeeded.” message on your screen.

11. Select OK, close the Command Prompt window, and check if the Teams Meeting option is now available in Outlook.

Method 3:

Update Registry Editor Keys
