We are running exchange 2013/office365 in a hybrid environment.
On two security groups, I add a group to the allowed senders list and then get the following error when I hit save:
Members can't remove themselves from security groups. Please reset the group to Closed for requests to leave.
I only see this error on two groups. The other 200+ worked fine when changing them. Any ideas?

You could use the cmdlet:
Set-Distributiongroup identity <DistributionGroupName> MemberDepartRestriction Closed.
And for better understanding of that cmdlet works check this out:

I ran that command and the error still happens. I actually tried that before posting this thread.
