please help me

Hello

if not need any data simple start appwiz.cpl and right click on exchange and remove. and follow wizard and remove role. if wizard says error please resolved issu and start again uninstall wizard.

On the server run setup /Uninstall.  You may have to remove the arbitration mailboxes that were created first and then the mailbox database that was created before uninstalling.

You can remove the Exchange organization from Active Directory, but it's not supported, and there's probably no real reason to do it.  If you want to tread into the unsupported area, here you go:

I don't believe that there's any supported way to remove the Exchange attributes from the Active Directory schema.
