365 can not send to groups onsite

[robjduk]

Morning all,

Yesterday I randomly discovered that 365 users can not email an onsite group. This was working fine a few days ago but now, randomly it claims we don't have permission. I have checked the permissions and it all checks out fine and even added myself personally to the group in question but it still fails to send.

Not long before this becomes an issue and wondered if anyone knew why this is happening all of a sudden? MS are in my bad books at the moment anyway and thinking I may just migrate back onsite and have done with it all.

Is it ALL groups? Can you create a new one and see if that works (just thinking something might have broken)

 

Failing that, MS support are quite helpful, I find
