Exchange 2007 - Safely Remove Storage Group.

      We are running Exchange 2007 on Server 2008 R2. A few months ago we had one storage group experience some corruption. I was fortune enough to be able to create another storage group and move all the mailboxes to it with no problems. My question is, can I safely remove the bad storage group? It still shows nearly 100GB being used on the disk, (edb file size). I also receive erros in the Event log as having a bad page link.
If so, are there any specific steps to remove it? There are no mailboxes attached to it.

Thank you

EDB files will never shrink. So even after you have moved those mailboxes to another database under another storage group it will continue to show the size of the EDB file (this is normal).

Before you can remvoe the Storage Group you need to make sure that the database that reside underneath the storage group have also been removed first.

Once their are no more databases under the storage group you can safely remove the Storage Group without any issues.

Are there specific steps to removing the database? I have attached a screen shot, when you refer to the database under the storage group do you mean the one I circled? I want to remove Storage Group 2. Do I simply unmount it and remove it?
Will SzymkowskiSenior Solution ArchitectCommented:
That is correct. Dismount the database, remove the database and then you will be able to delete the StorageGroup2 that you have outlined in your screenshot.

Thanks Will. Should I anticipate any problems doing this? I can't afford to have Exchange go down.
Will SzymkowskiSenior Solution ArchitectCommented:
No you should not have any issues with this. Storage Group and Database are managed separately. If there are no more mailboxes on this database you can dismount, remove, and then delete the Storage Group.
