When you need to communicate and collaborate with people outside your organization, Microsoft Teams has two options:
Does Teams Need A Microsoft Account
- External access - A type of federation that allows users to find, call, and chat with people in other organizations. These people cannot be added to teams unless they are invited as guests.
- Guest access - Guest access allows you to invite people from outside your organization to join a team. Invited people get a guest account in Azure Active Directory.
Note that Teams allows you to invite people outside your organization to meetings. This does not require external or guest access to be configured.
External access (federation)
Set up external access if you need to find, call, chat, and set up meetings with people outside your organization who use Teams, Skype for Business (online or on premises) or Skype.
By default, external access is enabled for all domains. You can restrict external access by allowing or blocking specific domains or by turning it off.
To configure external access, see Manage external access.
Note
Microsoft Teams free licenses do not support external access.
Guest access
Use guest access to add a person from outside your organization to a team, where they can chat, call, meet, and collaborate on files. A guest can be given nearly all the same Teams capabilities as a native team member.
Guests are added to your organization's Azure Active Directory as B2B users and must sign in to Teams using their guest account. This means that they may have to sign out of their own organization to sign in to your organization.
To configure guest access for Teams, see Collaborate with guests in a team.
