Hello
We have Exchange 2010/2013 hybrid environment.
We have a sensitive email distribution group and delivery is restricted to certain users only.
When a user who is allowed to send mail to this distribution group tries sending mail using outlook, he receive the error message:
You don't have permission to send to : GroupName
Additional Point : This user has multiple mailbox profile in his outlook. Only one of the mailbox in his profile is allowed to send message to this group.
Kindly help me in resolving the issue.
