Trying to decommision the old virtual exchange 2007 SP2(windows server 2008) server. We have upgraded to Exchange 2010(Windows server 2008 R2) which sits on its own virtual box.

I assume that the problem is with the schema version. Not sure how to go about it.

Any suggestions are greatly appreciated.

Here is the log:

Hi, Sunny
I have tried the first two methods. They didn't work. This is that old Exchange that caused me a lot of sleepless nights when its hub transport service stopped working and transition to Exchange 2010 went really bad with missing public folders.

I deleted Mailbox store from it without any issues. Public folders had to be manually deleted via ADSIedit. It kept complaining about replicas still existing.

Now, I just want to gracefullly shut it down and get rid of it.
