Configure Exchange 2003 as SMTP for Google Apps Business

Posted on 2011-05-02

We have Google Apps for Business and are using it to replace our Exchange server. However, some of our users need to send more than 2000 messages a day sometimes. I wanted to have those few users continue to use the Exchange server for outgoing email. The problem with this is that if they send an email to another domain user, it will go to their domain Inbox rather than Google's. I am keeping their Exchange email accounts active as we migrate.

User 1:

User 2:

User 1 -> User 2: Goes to Exchange Inbox.
User 1 -> External User: Goes outside of the domain to the WAN.

Any ideas?

    Additionally, can I add our Exchange server as an outbound gateway? Will that bypass the sending limit? I can't find anything that says it does or does not bypass the limit.

    Adding your Exchange server as an outbound gateway does not impact the sending limit.  You would also be sending all messages from Gmail to your Exchange server for relay outbound.

    To do what you want, you need to setup Dual Delivery with Google Apps Primary:
