Currently unity installed as UM with exchange message store. What is needed to have unity forward to external mailboxes ? thanks
If you want to forward all message for a given account to an external address, here's one way to accomplish this:
1. In AD, create a new contact record and assign it the external address.
1. Open the properties for the account that you want to forward.
2. Go to Exchange General > Delivery Options
3. Under "Forwarding address" choose Forward To, click Modify and choose the contact record you created above.
4. If you want messages delivered to both boxes, check the box that says "Deliver messages to both forwarding address and mailbox".
Hope this helps. If so, please rate the post.
