Can I delete First Storage Group database?

pc2005 asked
Last Modified: 2013-11-05
Hi, we have a mail server running exchange 2003, with 4 storage groups.  A while ago, we noticed our First Storage Group wasn't backing up.  After some investigation, we realised it seemed to be corrupted, although the only problem was the backup.  We moved all of the mailboxes into other storage groups which were backing up fine.  So far, so good.  So we still have our First Storage Group, which now has no mailboxes in it that we need to keep.  However the database is taking up 106Gb of space on the server, which we are really desperate for.  How would we go about deleting this database?  I don't want to cause exchange any problems.  As mentioned, there are only a few mailboxes still in the group, all old, and we don't need to keep them.  We now have 3 other storage groups holding our mail which are working fine.

Any advice would be appreciated - Thanks!

Yeah you can DELETE the stores in the first storage group.
do the following:-
1.Dismount all stores needed to be deleted(except public folders)
2.go to the locaiton where databases are located and manually delete them.Confirm their names and locaiton from the exchang system manager.DELETE .EDB AND .STM files.
3.DO NOT DELETE PUB1.EDB AND PUB1.STM these are public folders.

by default the System Attendant mailbox in only in the first mailbox store.
Missing System Attendant mailbox can cause problems at a later stage.

Thanks for your replies.  I have read the link about moving the system attendant mailbox, plus a few other sites, and it looks like I can do the following:  Dismount the mailbox store in first storage group, delete old priv.edb and priv.stm from the disk.  Re-mount the mailbox store in the first storage group, which will create a new empty priv.edb and will automatically create a new system attendant mailbox.  The backup of the priv.edb doesn't work, but there are no mailboxes in here that I need to keep.  The backups of my other storage groups are working fine.  Can anyone see anything stupid here that I am doing (or missing!), are there any other system mailboxes I need to be aware of?  Will I need to restart any exchange services and if so at which point should I do this?  Will I need downtime to do any of this or should I be able to do it while my users are logged in?  Thanks again and sorry for the dumb questions...!
