Invite an External User via Entra ID

This guide walks you through the steps to invite a guest user (external collaborator) to your Microsoft 365 tenant using the Microsoft Entra ID portal. This is commonly used to grant access to Teams, SharePoint, or other internal resources securely.

Before proceeding, make sure:

• You have Global Administrator or User Administrator permissions.
• External collaboration is enabled in your tenant:
• Entra ID > External Identities > External collaboration settings.

How to Invite a Guest User

1. Go to Microsoft Entra Admin Center https://entra.microsoft.com
2. Navigate to Identity > Users > All users
3. Click + New user
4. Select Invite external user from the dropdown.
5. Fill in the invitation details:
   • Name: (e.g., John Doe)
   • Email address: (e.g., johndoe@example.com)
   • (Optional) Add a personal message
   • (Optional) Assign to a group
6. Click Invite

The user will receive an email invitation to join your organization. Once accepted, they will appear in your directory as a Guest user.

Notes:

Guest users will have the suffix #EXT# in their UPN format. You can manage guest access and permissions via Entra roles or group memberships. Users must accept the invitation before being able to access resources.
