Invite External Guests via the Microsoft 365 Admin Center

Use the official Microsoft 365 Admin Center to invite Gmail or Yahoo accounts, granting them controlled access to your organization's resources.

By adding external users as guests in Azure Active Directory (Microsoft Entra ID) via the Admin Center, you maintain security and control over what they can access. The invited user can authenticate using a Microsoft account linked to their existing Gmail or Yahoo address.

1
Sign in to the Admin Center

Go to the Microsoft 365 admin center and log in with your global admin or user admin credentials.

2
Navigate to Guest Users

In the left-hand navigation menu, expand 'Users' and then select 'Guest users'.

3
Add a Guest User

Click on 'Add a guest user'. This will redirect you to the Microsoft Entra admin center (formerly Azure AD) to configure the invitation.

4
Enter User Details

Provide the user's Gmail or Yahoo email address and display name. You can also add a personalized welcome message.

5
Send the Invitation

Click 'Invite' to send the invitation email. The recipient can then accept the invite, create or sign in with a Microsoft account tied to their email, and access the shared resources.

Frequently Asked Questions

Do Gmail or Yahoo users need to pay for a Microsoft account to access shared files?

No, creating a Microsoft account using their existing Gmail or Yahoo email address is completely free and allows them to authenticate as a guest securely.

Can I limit what guest users can see in my Microsoft 365 organization?

Yes, guest users only have access to the specific resources, SharePoint sites, or Teams channels that you or your administrators explicitly share with them.

Why is the invited guest user unable to access the shared link?

Ensure that external sharing is enabled in your organization's SharePoint or OneDrive admin settings. Sometimes, organization-wide security policies block external guest access by default.
