6] Re-register Teams add-in DLL file

The Microsoft.Teams.AddinLoader.dll file is the Dynamic Link Library (DLL) that ensures the Teams Meeting add-in in Outlook works correctly. If this DLL file is corrupted, you will experience this issue.

Here are the steps to do that:

First, open Run using Win+R and enter %LocalAppData% in the Open field.

In the available location, move to the Microsoft > TeamsMeetingAddin folder and then open the folder with the latest version number. Then, open the x86 folder.

From the address bar, copy the path of this folder.

The copied path will look something  like the below address:

C:\Users\sriva\AppData\Local\Microsoft\TeamsMeetingAddin\1.23.33413\x86

Now, open Command Prompt with administrator rights using Windows Search.

After that, enter the below command:

cd C:\Users\sriva\AppData\Local\Microsoft\TeamsMeetingAddin\1.23.33413\x86

In the above command, replace the above path with the previously copied location.

Next, enter the following command to re-register the DLL file:

regsvr32 Microsoft.Teams.AddinLoader.dll

Once you see the “DllRegisterServer in Microsoft.Teams.AddinLoader.dll succeeded.” prompt, exit Command Prompt and restart your PC. You can now launch Outlook and see if the Teams Meeting option works properly.
