Forwarding email to external user from Exchange 2010

I am trying to set up forwarding from a mailbox on my domain to a user on a different domain outside my organisation.

I have tried the following but the user hasn't received any messages forwarded on from the recipient mailbox.

Set-Mailbox -Identity Carina Fagan -DeliveryToMailboxAndForward $true -ForwardingSMTPAddress

Is there anything else i should be doing?

Many thank,

The standard way is to use ForwardingAddress and not ForwardingSMTPAddress, ForwardingAddress  will require that you create a mail contact, if you still want to use ForwardingSMTPAddress read the below

is this user defined as mail contact in Exchange?
When you try to do this via GUI, you will need to select user from GAL, so that means that you need to have this external user created as mail contact first.

Hi Both,

I used the exchange management shell and when i search again to see if it is set up i see the following (see attached screenshot).

Are you suggesting that i need a mail contact set up as well?

I sent you all the details :) did you read the article I gave you ?

Or just create a mail contact inyour AD with as external email address and use the ForwardingAddress  intead of ForwardingSMTPAddress

Yes, thank you. I have set up the remote domain as per the article and have sent an email to the recipient mailbox, unfortunately the external user is on leave this week so is only checking emails sporadically so i might not know for a while if it has worked or not.

Thanks for your assistance.
you can easily check in your logs

For me the remote is not require for mail forwarding. First you have to create mail contact using either exchange management console or exchange management shell.

Once done, set mail fowarding either using exchange console or exchange powershell

Send a test email. You then do message tracking to look where is go and why does it fail if any

Email forwarded successfully. Thank you.
