Redirecting SBS2003 to another host
I'm doing a migration from Exchange 2003 to Google Apps for Business. This is not the first time I've done this and it won't be the last. It's got me wondering though...
To speed up the propagation issue, is it possible to configure the Exchange server (usually SBS2003) to redirect inbound mail to the Google mail server rather than receiving and processing it?
If this is possible, then I don't have to wait until after the DNS propagates - I can just migrate the users away safe in the knowledge that legacy emails will still find their way to the new email account.
Any ideas?

@ChrisHanna_MVP: It's an Exchange 2003 box that's 5 years old. This is a move in preference to a replacement server.
With regards to TTL values - Where do you set them? I can't see any mention of them in Plesk so I'm a bit puzzled.
Also, are there any downsides to having a low TTL value? If not, why is it that they are not all as low as possible by default?

Not sure what Plesk is, but in essence, who ever has access to create and modify your public DNS records should be able to, and know how to change the TTL
The reason they are not set low is because they rarely change and therefore having a high TTL reduces network traffic

The question I have to ask is why the move? they already own a perfectly good mail server
So now you're moving them to a new system they have to pay for?
