Dear AJCD,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
As per your description, based on my test, I'm afraid to say that, I also meet the same behaviour as like you described above. Using Microsoft 365 Group in Yammer and Teams @ mention feature not show up. And @ mention feature work if I send a message to a specific person in Yammer (not group).
Here is my test screenshot for your reference:
It seems that due to limitation we cannot user in Microsoft 365 Group. Personally, I completely agree with you, this is indeed a good addition to the current features of Microsoft Yammer and Teams. It would be definitely ideal if we can add feature to @ mention Microsoft 365 Group in Yammer. Thank you for bringing thing to our attention.
I request you, please send/provided feedback to related Yammer development team via Microsoft Yammer feedback portal, so that they can get notice about it. This is the best platform to let related team hear from you and make the products and services better for you and others.
Your understanding and patience will be highly appreciated. I hope that you are keeping safe and well!
Sincerely,
Waqas Muhammad
