If you’re getting a popup on a web page in Microsoft Edge And Hover state Do the following. Click on the three dots menu Choose settings Go to Privacy, Search and Services and make sure Tracking Prevention is set to Balanced. If this doesn’t work it’s likely you have an extension installed that is causing some sort of popup.

I’ve had this a few times, and there are a few reasons, but we’ll just cover the most common here, and that’s cached credentials that have changed. If you see this, start up the Credential manager.

Choose Windows Credentials Search for msteams Entries Remove each of these, and Teams should start again and prompt you for new credentials.
