Guest experience in Teams
When a guest is invited to join a team, they receive a welcome email message. This message includes some information about the team and what to expect now that they're a member. The guest must accept the invitation by selecting Open Microsoft Teams in the email message before they can access the team and its channels.
All team members see a message in the channel thread announcing that the team owner has added a guest and providing the guest's name. Everyone on the team can identify easily who is a guest. A tag in the upper-right corner of the channel thread indicates the number of guests on the team and a (Guest) label appears next to each guest's name.

The Guest user access restrictions policy in Azure Active Directory (Azure AD) determines permissions for guests in your directory. There are three policy options.
- The Guest users have the same access as members (most inclusive) setting means guests have the same access to directory data as regular users in your directory.
- The Guest users have limited access to properties and membership of directory objects settings means that guests don't have permissions for certain directory tasks, such as enumerating users, groups, or other directory resources using Microsoft Graph.
- The Guest user access is restricted to properties and memberships of their own directory objects (most restrictive) setting means guests can only access their own directory objects.
