External guests

Seamless controls guests via guest templates, from invitation to deletion.

Note

A guest is an external person who signs in to your tenant with their own account, e.g. an account from another Microsoft Entra organisation, a Microsoft account or an email one-time passcode. A user of type Guest is created for them in your tenant. More information: Properties of B2B users

Lifecycle

Phase	What happens
Template	Admins define per guest type how guests are invited and managed.
Invitation	Users invite guests in the Seamless App.
Approval	Approvers review the invitation if the template requires it.
Acceptance	The guest accepts the invitation. Invitations that are not accepted are deleted after the deadline.
Operation	Background jobs check inactivity and due reviews.
Blocking	Inactive or unreviewed guests are blocked.
Deletion	Guests are deleted automatically after the deadline if the template provides for it.

Note

Unlike workspaces, Seamless deletes guests automatically if this is configured in the templates.

Guests register themselves

Instead of inviting each guest individually, embed a self-service form on your website. People with an allowed domain register themselves. They automatically receive a guest template, a primary contact and access to the selected teams.

Guests maintain their own details

If a guest is missing details such as company or job title, send them a request. The guest completes their details in the guest portal themselves, without signing in to your tenant.

Who does what

• Admins set up templates with rules for guests in the Admin Center. They can adjust all guests at any time.
• Inviters invite guests in the Seamless App and are then responsible for them. Admins can also invite guests in the Admin Center.
• Primary contacts are responsible for guests, carry out reviews and, depending on the template, can block, delete or hand over guests.
• Guests work in the teams and sites they have access to.
