Migration to EU, loss in functionality

Occasional Contributor



We wish to migrate our Yammer to EU. We know we need to provision the Yammer. However, we are unsure whether the restriction below still apply? As this is an old post 2019, and there has been a more recent update in 2021 --> Guest Access in Yammer using Azure AD B2B is now in preview! - Microsoft Tech Community.


Am I looking at the same use cases? If so, which one is valid?

I had the same question about this old post from 2019 and the answer from Microsoft Support was that this still applies.
