I have an exchange 2013 server. We have mail contacts set up for some external contacts.
There are several distribution lists which contain these mail contacts.
When an internal user inspects the distribution list through outlook, the mail contacts are not shown.
When I open exchange shell and run
I get the full list of users including the mail contacts.
I have checked the contacts and none of them are set to 'hide from address lists'.
Does anyone know how to include these recipients in the list as far as outlook is concerned?
