Enabling guest access in Microsoft Teams: patience, patience…

I wanted to enable guest access in Microsoft Teams, in order to be able to invite external users to a team.

There are some interesting checklists and how-tos:

Microsoft Teams Guest Access checklist

Turn on or off guest access to Microsoft Teams

But the most important thing to know is in the second document: It takes 2 hours to 24 hours for the changes to be effective across your Office 365 organization. We are maybe not used to waiting anymore when it comes to IT stuff, but in my case it really took more than 15 hours for the setting to become active. So be patient :–)

Microsoft Teams for Mac: login fails with endless loop

I wanted to use the Microsoft Teams app on macOS to login to my personal Office 365 account, but I recently used it to login to my corporate account. That did not work out very well: Teams got into an “endless loop” asking me to sign in over and over again. It looks like Teams has some issues when switching between different accounts.

I got this solved by opening Keychain Access, and deleting the entry called Microsoft Teams Identities Cache. After that, I could sign in to Teams again with the correct account.
