We have migrated from 2007 to 2013 and are now trying to decommish Exchange 2007 from our environment.
I have migrated the Public Folders from 2007 to 2013 but I cannot remove the Public Folder database from 2007.
I get this error:
Remove-PublicFolderDatabase : Object is read only because it was created by a future version of Exchange: 0.10 (14.0.100.0). Current supported version is 0.1(8.0.535.0).I have made sure all replicas and public folders are gone from the database, and I've also tried dismounting the DB, deleting the EDB file, and remounting. Same error every time.
I have read multiple articles on the subject but most of them pertain to a 2007>2010 migration and involve running the Remove-PublicFolderDatabase cmdlet on the 2010 server. Unfortnately 2013 does not include that cmdlet and the only other option I have read about involves using Adsiedit, which I REALLY like to avoid as it's not a supported method.
Can anybody help me out?
