Configure Guest Accounts via Microsoft Entra ID

The standard and most secure method to grant Yammer access to users without a corporate email is to invite their personal or external emails as guest users in Microsoft Entra ID.

By configuring these employees as external guest users, you can bypass the need for a corporate email while still maintaining administrative control over their access to the Yammer community.

Enable External Access in Microsoft 365

Log in to the Microsoft 365 admin center, navigate to Settings > Org settings, and confirm that Yammer (Viva Engage) external access and guest membership features are enabled for your organization.

Invite Users via Microsoft Entra ID

Open the Microsoft Entra ID admin center. Go to Users > All users, click on 'New guest user', and invite the employee using their personal or alternate email address.

Assign to the Microsoft 365 Group

Once the guest account is created, navigate to Groups in the admin center and add the new guest user as a member of the specific Microsoft 365 group connected to your Yammer community.

Share the Community URL

Provide the guest user with the direct URL to the Yammer community. They can use this link to log in with their invited email address and access the network.

Security Policy Reminder: Always review your organization's security and guest-access policies before inviting external email addresses to internal communications networks.

Frequently Asked Questions

Can an employee access Yammer with a standard Gmail or Yahoo account?

Yes, provided an administrator invites their Gmail, Yahoo, or other personal email address as a guest user via Microsoft Entra ID and adds them to the relevant Microsoft 365 group.

Why isn't the guest user receiving the Yammer invitation?

This typically happens if your organization's Microsoft 365 guest-access policies restrict external invitations, or if the automated invitation email was filtered into the user's spam or junk folder.

Do Yammer guest users require a paid Microsoft 365 license?

No, guest users added through Microsoft Entra ID typically do not require a separate paid Microsoft 365 license to access and participate in a Yammer community.
