Windows Defender Error with Teams Video Meeting

This article applies to: Microsoft Teams

When trying to launch a Microsoft Teams video meeting, an error message may appear: "Windows Defender has blocked some features of this app."

Clicking Allow Access from the options Defender presents triggers a request for administrative credentials.

Users who have administrative privileges for their computer should enter them.

Users who don't have administrative privileges should select Cancel, then initiate the call again. They will not get the Defender warning the second time. All features will still be available in the meeting.
