We have recently migrated from Exchange 2007 to 2010.
All is working well except we cannot completley remove 2007 from the old server.
All bar the mailbox role removed cleanly, it complains that there are files/indexes in the Public folder.
Have been through many, many articles used ADSIEdit to reset the public folder etc etc....but all attempts to either move or delete those files/indexes fail for one reaosn or another, usually with an error message that the folder itself does not exist.
So can I go into ADSIEdit and remove the old 2007 server from AD that way?
It does not seem to be causing any problems, the physical server has been turned off now for a few weeks (not while I was doing the above of course!) and I see no impacts. But would like to do it properly as that server and I have 'history' - (let me just say that I know what MS mean when they say they do not support demoting a Domain Controller that has Exchange installed!! :-( )
