Exchange Standard Version 14.2 (Build 247.5)
Windows Server 2008 R2 Enterprise
Active Directory 6.1.7601.17514
When I add a security group to a mailbox with Full Mailbox permissions, whether I do it in the Exchange Management Console with the mouse, or in the powershell console, none of the members of that security group see the mailbox in Outlook.
If I add the users the same way, but individually (not as part of a security group), the mailbox will show up and map.
I'm trying to get this to work with security group so it will be less of a mess managing all the users individually.
