How you can prepare:

Review the following resources and ensure .Net 4.8 and WebView2 are installed to run the Teams Meeting Add-in in Outlook:

NOTE:  In some support cases engineers found that if .Net 4.8 or Webview2 were not installed, that installing them helped address the issue with the Teams Add-in becoming disabled.

These steps will help verify if .Net 4.8 is installed:

​​​​​​​How to: Determine which .NET Framework versions are installed

The steps below taken from the Use Registry Editor section in the article above.

  1. In the Registry Editor, open the following subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full. If the Full subkey isn't present, then you don't have .NET Framework 4.5 or later installed.

  2. Check for a REG_DWORD entry named Release. If it exists, then you have .NET Framework 4.5 or later installed. Its value corresponds to a particular version of .NET Framework. In the following figure, for example, the value of the Release entry is 528040, which is the release key for .NET Framework 4.8.

These steps will help verify if WebView2 is installed

Microsoft Edge WebView2 and Microsoft 365 Apps

The steps below are taken from WebView2 Runtime installation section in the article above.
