Where Microsoft Teams fits
Use it when your organization coordinates communication through Microsoft accounts.
Check before you choose
Check whether you need the personal or organizational account experience before installing.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
Choose a communication tool around the people who need to join it. Account requirements, meeting access and conversation privacy can matter more than a long feature list.
