Office 365 - Teams (How To) Add a Guest to Teams

Microsoft has begun to roll out the ability to add external users as a guest in Microsoft Teams. Now guests in Teams have full access to Team chats, meetings and files. External guests who are invited to a Team will need to use an Office 365 account from their own organization or have a free Microsoft account associated with their email address. If they don't yet have one, they will be directed to create one for free.

How Do I Add a Guest to Teams?

1. Find the Team you want to add your external team member to in Teams. 
2. Select the three dots on the right hand side of the Team name. From here, select Add Members. 
3. Type in the external email address of the member you want to add and click Add. 
4. Once you do this, a dropdown selection will allow you to add the member to the Team. 
5. Once complete, click close and the member is now part of that specific team.
