Invited to external M365 group - how add to Outlook 365

Hi all,

 

I have been invited to an M365 group from an external organisation.  I have accepted the invitation.  I can view the group via the link in the email.

 

I expected the group to appear in Outlook 365 but it hasn't.  Can I add the Group to Outlook manually, or at all?

 

thanks

    When you are invited to a Microsoft 365 Group from an external organization, you are added as a guest user. Unfortunately, guest users do not get full integration with Outlook like internal members do. That means:

    • The group won’t automatically show up in your Outlook client.
    • You can’t manually add it to your Outlook like a native group.
    • You can access it via the web link, but not through your Outlook 365 interface.
