Completely remove exchange from domain

We have moved to Gmail and need to remove an Exchange 2003 server and Exchange 2010 server. SInce the users do not have to be migrated anywhere how do I remove the servers? Most docs I have found always refer to moving the users first elsewhere, then uninstalling Exchange, but we do not need to do that.

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That's the ideal way, else you can use ADSIEdit tool to clean it. However, if you never used it before, better call MS.

If you don't need the data, then simply mail disable the users to clean the database.
Once you have removed all of the regular users, flush out the public folders as well.
It is documented on TechNet on how to remove Exchange 2010, so do that, including removing using add/remove programs.

Then follow the same documented procedure to remove Exchange 2003.

Although I wouldn't be surprised if you are back on Exchange. I am currently migrating two clients a month OFF GMail. I can't name names, but one of their major "wins" here in the UK I brought back last year.

I am hoping to move back to Exchange someday, this was not my idea and I argued against it. We will spend as much each yearly for mailboxes on Gmail as it would have cost to buy the server license, Exchange license and CALS one time...
AmitIT ArchitectCommented:
Users who are use to Outlook and Exchange can hardly use other email technologies. As 99% client machines runs with windows with office and till now no one was able to replace it.

In your case, If you cannot remove gracefully, use adsiedit to remove it. Steps are below
