We have accidentally put both our mailbox database and Public Folder database in the first storage group when we were setting up Exchange 2007. Is it possible to move the Public Folder database to the second storage group? I have tried deleting the Public folder Database but get an error that the "database contains replicas." (We have two other new Exchange servers with public Folder Databases). I have not set up any replication (or any public folders yet) on any of the servers so this must have happened automatically. The only Microsoft help files seems to suggest using the Moveallreplicas.ps1 script (MoveAllReplicas.ps1 -Server MySourceServer -NewServer MyTargetServer) to replicate the folders to another database. (Presumably one of the public folder existing databases on one of my other servers - as you can't have more than one public folder database per server). Then delete the Database. Then recreate the database in the Second Storage group. But, if I recrate the new database in the second storage group will all the system folders be there (and so would I need to delete the replicas I had moved somehow (how?)) or would have to replicate the folders back to the newly created database (how?)?

Exchange 2007 doesn't "need" a PF database. unless you are using it to support Outlook 2003 or public folder "content" which you said you are not, i'd just delete the whole thing, and make a new one. Another option would be to focus on the mailboxes - not the public folders. you can move the mailboxes to a database in another SG, then delete the mailbox db.Mike Crowley: MCT, MCSE, MCTS, MCITP: Enterprise Administrator / Messaging Administrator

I think you can also simply move the files and mount the DB under the new SG and then use the move-mailbox -configurationonly on the users, but the above two are a sure thing with no research involved. http://technet.microsoft.com/en-us/library/bb123954.aspx Mike Crowley: MCT, MCSE, MCTS, MCITP: Enterprise Administrator / Messaging Administrator

Id recommend the second method from Mike, create a new storage group and move mailbox into it, which is the safest way to separate the mailbox database and public folder database
