How to uninstall Exchange 2000 from Win 2003 Server

Hello,

I mistakenly installed Exchange 2000 on Win 2003 Server, not realizing it's not supported.

When I try to remove it, I get an error message saying "One or more users currenlty use a mailbox on this server.  These users must be used to a mailbox store on a different server."

I don't want to move the mailbox store to a different server.  Nor do I have another server to move it to (and wouldn't know how if I did).  I just want to get rid of Exchange 2000 altogether, so that I can install Exchange 2003.

(On that note, upgrading from Exchange 2000 to 2003 on Server 2003 doesn't work either, so it appears removing Exchange 2000 is my only option).

If you do that then your mailbox store will be lost.  Don't see any way around it.

I don't mind the mailbox store being lost.  There's nothing in it.  

Problem is it won't let me uninstall because of of the user associated to the mailbox.  How do I get rid of that?

Have you checked Systems Manager to see the user's mailbox?

I don't see anything in Exchange Systems Manager that would show a mailbox.  The mailbox store itself is not mounted, because Exchange 2000 won't run on Win 2003.

I thought maybe I can do something in AD Users and Computers, but there is nothing I can see that would allow me to get rid of a mailbox.

Thanks!

Here is how I ended up working it.  It turns out that if you upgrade the non-working version of Exchange 2000 to SP3, you can then upgrade it to Exchange 2003.
