Users are currently experiencing outage to expected functions inside Microsoft Teams. Vital functions inside the apps like the ability to do calls, video, meetings etc, are broken for a random group of users across a multitude of user groups.
Around where I am based the discussion started to show itself at the end of january. Troubleshoothing has been ongoing since then, with limited results to an acualt fix.
The temporary fix have been around rolling back to version 1.4 for users that have experienced the issues. But, as Teams gets updated automatically, this is very temporary.
There has also not been very clear as to why only some users have been affected.
During the last week or so, this has become more clear.
Read on for details and a temporary workaround until this gets resolved
