Forwarding an email to an external address is really very easy in a UNIX/LINUX based Email Server but in exchange server its a little bit tricky task. Follow the under given steps and there will be no problem in creating a forwarder in exchange server;
First, you’ll need to create a mail-enabled contact:
Open the “Active Directory Users and Computers” tool. Expand the organization, highlight the “Users” folder, and right-click; from the pop-up menu, select “New, Contact.”- In the “New Object – Contact” window, choose a name for the contact and click Next. It’s a good idea to use a standard naming convention for all of these contacts; that makes them easier to identify at a glance.
At the next window, make sure the checkbox for “Create an Exchange email address” is checked, and hit the “Modify…” button. Next, choose “SMTP Address” as the address type, then enter the appropriate email address and click “OK.” Click “Next,” and finally, “Finish.”
The contact has now been created; the next step is to configure mail forwarding.
In the Active Directory Users and Computers snap-in, double-click on the user whose mail you want to forward.- Click the “Exchange General” tab, then click “Delivery Options.”
- In the section for the forwarding address, check the “Forward To” radio button, then click the “Modify” button.
- Enter the alias of the mail-enabled contact you’ve created, and hit the “Check Names” button. If everything is working correctly, the name will appear underlined once the server has resolved it. Sometimes you might need to wait a moment for the recipient service to update its list.
If you’d like, you can also check the box to “Deliver messages to both forwarding address and mailbox.” Click “OK” on each of the screens, and you’re done.
Note: You might not want the mail-enabled contact to appear in your organization’s Exchange address books. To hide the address, open the contact within the Active Directory console and go the the “Exchange Advanced” tab. Check the box that says “Hide from Exchange address lists.”
