Office 365 Hybrid Mail Flow Restrictions

[Davit2005]

Hi All,

We have a hybrid setup with staff remaining On-Premise and Students mailboxes going to Office365.

 

We have a Universal Group which has been sync'd with Office 365 but are trying to restrict which staff can send to the group.

 

The 'Require that all senders are authenticated' is sync'd along with Reject messages from where we have selected the Student Mail Group and that prevents Students sending to the group.

 

How can we only permit certain staff to be able to send to the group?

 

We want this to be as easy as any members of staff that have got permission to send to the group being able to send directly from their On-Premise mailbox without the need to log in to Office 365.

Bounce, plenty of views but no answers

 

Think I may have found a fix, I had to change an attribute on the email group field, dlMemSubmitPerms , created a security group and put this group in the attribute. Tried a send and it didn't send the email to the group as I am not a member of the group, then I made my self a member of the group and the email got to the student email group
