What the guest experience is like
When a guest is invited to join a team, they receive a welcome email message that includes some information about the team and what to expect now that they're a member. The guest must redeem the invitation 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. As shown in the following screenshot of a sample team, a banner indicates "This team has guests" and a "GUEST" label appears next to each guest's name.
The following table compares the Microsoft Teams functionality available for an organization's team members to the functionality available for a guest user on the team.

Guest access vs. external access (federation)
External access (federation) and guest access are different:
Guest access gives access permission to an individual. External access gives access permission to an entire domain.
Guest access, once granted by a team owner, allows a guest to access resources, such as channel discussions and files, for a specific team, and chat with other users in the team they have been invited to. With external access (federated chat), the external chat participants have no access to the inviting organization’s teams or team resources. They can only participate in one-on-one federated chat. Tenant admins can choose between the two communication options depending on which level of collaboration is desirable with the external party. Admins can choose either approaches or both, depending on their organizational needs, but we recommend enabling guest access for a fuller, collaborative Teams experience.
For a detailed comparison, see Manage external access.
