Split-Domain Routing When Migrating from Exchange to Hosted Exchange

This article covers split-domain routing when migrating from a local Exchange Server to Hosted Exchange accounts. First, you must enable Split-Domain Routing within the Customer Portal. (See Part II for SDR setup.) After setting up domain routing, you can then begin migrating accounts over. After a User is setup on Hosted Exchange, you will need a way to get local messages forwarded to them. Use the information below to forward email from your local email server to a hosted Exchange mailbox.

Alternate Email Addresses:

Every user has an alternate email address in the format of:


For example, if you have a user account named jdoe hosted for domain company.corp on the exg7.exghost.com servers, then this user account would have an email address of jdoe@company.corp and an alternate email address of:


Our current alternate domain name is:

    EXG7: fwd7.exghost.com

Microsoft Exchange:

Follow the below procedure to forward email from a previous Exchange server to Hosted Exchange:

1. Open Active Directory and go to the Users container.

2. Create a new Contact using the alternate email address for that user.

3. Now find the User account in Active Directory, right-click and go to properties.

4. Locate the Exchange General Tab.

5. Click the Delivery Options button.

6. Under Forwarding Address, select the Forward to: option button and then click Modify and enter the name of the Contact that you just created.

7. You may also select to deliver email to the new hosted server and the users old local inbox. When done, click OK and Apply.
