Create a Yammer Community for External Guests

Since the direct admin invite button has been removed, creating a specific community permitted to add external members is the standard approach for collaboration.

Microsoft has integrated Yammer's external access with Microsoft 365 guest management. You can no longer invite external users directly to the entire internal network. Instead, you must host them in specific, supported communities.

1
Create a new community

Log in to Yammer and select 'Create a community' from the left navigation pane.

2
Enable external access

While configuring the community details, check the specific option that allows you to invite people from outside your organization.

3
Send email invitations

Once the community is created, navigate to the 'Add members' field, type in the external user's email address, and send the invitation.

Frequently Asked Questions

Why is the 'Invite Users' option missing from my Yammer admin center?

Recent updates to Yammer integrated guest management more closely with Microsoft 365 Azure Active Directory (B2B). Direct broad invitations from the admin center were removed to improve security. External access is now managed at the community or external network level.

Can I add external guests to the 'All Company' group in Yammer?

No. The 'All Company' group is strictly limited to internal users. To collaborate with people outside your organization, you must create a new community with external access enabled or set up an entirely separate external network.

Do external users need a Microsoft 365 license to join my Yammer community?

External users typically do not need their own Yammer or Microsoft 365 paid license to participate as guests. They can join your Yammer external community for free, provided your organization's IT policies allow guest access.
