Un-install Exchange 2003 from SBS 2003

Hi Experts,

I have a SBS 2003 with exchange environment that I migrated over to exchange 2010 on a new machine.

I want to un-install the old exchange 2003 and decommissioned the this SBS2003 machine.

I am getting the attached message when I try to un-install exchange 2003 from the old SBS machine.

Error Message:

"The component "Microsoft Exchange Messaging and Collaboration Services"
cannot be assigned the action "Remove" because: -One or more users currently "

Any thoughts ?

You have users still on the machine. That could be a mail enabled user, rather than a mailbox enabled user.

Use the method I have outlined on the link below to find the user and remove them:

I would also ensure that you have removed public folders and dropped the public folder and mailbox database before you try again. Exchange will not allow you to drop either if there is still data on them, which will also stop the uninstaller.

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Thank you, there is a System Mailbox {E353F16D-AA5A ....... } account when I did the Advance search in ADUAC.

Should I delete the exchange attribute form this account too ?

I deleted the exchange attribute from the other user accounts.

The system mailbox is unique to each server - it will not stop the uninstall from completing.
