We are in the process of migrating from Exchange 2007 to Exchange 2013. All platforms have been built and are running as expected.
During the initial creation of the mailbox databases, one was created that will no longer be used.
I unmounted the database. Then used the trashcan icon to delete the database. I received the standard message that the database file would need to be removed manually (no surprise).
I navigate to the Mailbox directory, highlight the folder for the erroneous database and hit the delete key. I get the standard "Are you sure..." message and click 'Yes'.
Much to my surprise, I get a warning that 'noderunner.exe' is accessing files in this folder. Why? I had the management console remove all references so I should be able to delete this. I have rebooted to try and clear any active processes, but 'noderunner.exe' grabs it immediately.
As such, I can not remove this folder that Microsoft states I can. What is the trick that is not documented to allow for the deletion of this folder?
