Guest user was invited to SharePoint and added as guest user to our Azure tenant. Guest user has a Microsoft Outlook account without 365.
Our Yammer network is migrated and in Native Mode, situated in EU region.
When trying to invite the guest user I get an geo based error.
When trying to use the B2B collab option in the guest user profile in our Azure portal, to convert user it says "conversion failed".
When adding a Microsoft Business Standard license to the guest user, it still gives the geo based error.
When adding the user to the connected O365 group from the Office 365 Admin Center, it succesfully adds, but the user does not show up in the Yammer community.
Any thoughts on how we can succesfully invite guest users without exisiting AAD connected account?
