Using Exchange 2013 CU5 and are unable to configure forwarding in the Exchange Control Panel. We can find recipients from the Select Recipient dialog box, but the recipient's name never populates in the "Forward email to the following recipient field".
Same issue applies when selecting recipients for the Message Delivery Restrictions Accept From/Reject From fields.
I can populate the Message Size Restrictions field with a number, so the issue seems to be isolate to configuring the recipients field in any of the Mailbox Features tab.
I have no issue populating recipients in the Mailbox Delegation tab.
No issues configuring forwarding through PowerShell.
Any ideas on how to troubleshoot would be nice!!
