Note: You must be a team owner to add a guest in Teams.
Add a guest to your team
Guests must have a Microsoft 365 work or school account. If the guest doesn’t yet have a Microsoft account associated with their email address, they will be directed to create one for free.
Note: After you add a guest to a team, it may take a few hours before they have access.
To add a guest to your team in Teams:
-
Select Teams 
and go to the team in your team list.
-
Select More options 
> Add member.
-
Enter the guest's email address. Anyone with a business or consumer email account, such as Outlook, Gmail, or others, can join your team as a guest.
Note: If you receive a "We didn't find any matches" error while trying to add a guest, your organization doesn't allow guests.
-
Add your guest's name. Select Edit guest information 
and type a friendly name for them. Be sure to take the time to do this now—you’ll need the help of an IT admin to do it later.
-
Select Add. Guests will receive a welcome email invitation that includes some information about joining Teams and what the guest experience is like.
Note: When you add a guest, only their name gets added to their profile card. To add or change other info (such as phone number or title), you'll need to contact your IT admin.
Identify guests on a team
To see if a team has any guests, just look below the heading where the team name shows up.
You can tell if someone is a guest by looking anywhere their name appears—the word “Guest” appears after it. You can also see everyone’s roles in the Members tab of a team. Go to the team name, and select More options > Manage team > Members.
Guests have fewer capabilities than team members, but there's still a lot they can do in channels, where the work actually gets done! Team owners can set guest permissions for channels. To set guest permissions:
-
Select Teams on the left side of the app.
-
Go to the team name, and select More options > Manage team.
-
Select Settings > Guest permissions. Check or uncheck the permissions you want to allow.
Your guests can now collaborate with team members in channels.
