Yammer Licence Error

MVP

Can anyone shed any light on this issue. For over a year now I have been signing into Yammer with my corporate credentials, backed by Azure AD, all worked fine. However recently I have started getting this error:

 

You don't have a license to use Yammer with the account assigned to you by your work or school. Ask your admin to assign one to you.

 

I assume something has been done at the O365 level to cause this, the issue I have is not that this breaks access to my corporate network, but that I am also a member of a number of external networks provided by Microsoft, and I can no longer access these. These networks are used by many people and do not, as far as I know, require a licence. How can I get access back to these networks?

Someone at your site removed the Yammer license from your account. That would revoke access to both the internal network and any external networks you participate in.
