How do I add guests to a team?
If you're a team owner, you can invite guests from outside your organization to your team.
Go to the team name, click More options > Add members, and then enter the guest's email address.
Notes:
Guests just need a valid email address.
If you receive a "You are not authorized" error while trying to add a guest, your organization doesn't allow guests. Contact your IT admin for more info.
Now that you have guests on your team, you might be curious to know what they can do while they're here or what settings you can change for them.
