I used the following format in Exchange 2013 shell:
Set-Mailbox -Identity "Ryan" -DeliverToMailboxAndForward $true -ForwardingSMTPAddress Ryan@yahoo.com
I do not see the external email address or the forward checkbox checked under the user mailbox settings in the ECP, but the settings seem to have been applied (no errors after command in exchange shell).
I am able to see under delivery reports that a test email is trying to forward to the email address (see below), but it is being delayed. Can i get more detail than the delivery report below? And how can I verify forward settings in exchange shell? Need some help troubleshooting and fixing this issue.
