There is a Shared mailbox set for AutoReply with Powershell command:
Set-MailboxAutoReplyConfiguration "firstname.lastname@example.org" -AutoReplyState Scheduled -StartTime "3/24/2014" -EndTime "9/15/2099" -ExternalMessage "Test message" -InternalMessage "Test message"
but somehow it does not work (the strange is that there are other shared mailboxes and only this has issue), so no reply comes back for the test attempt.
Basically at this mailbox (however also at the working ones), there is Forward to address set on server side, also the 'Deliver message to both forwarding address and mailbox' is set.
Do you have idea where could be issue, did someone had similiar problem?
