Remove RSG from Exchange 2007

I have a fully patched Exchange 2007 Server and I see there is an RSG there taking up 40GB of Disk Space with an edb which has a date from 2 years ago.

I suspect it's not wise to just delete it, but I can't see any reference anywhere to an active RSG? How can I get a list of RSG's or How can I remove the RSG safely with no loss of data? I presume being an RSG no part of that EDB is actively linked to the current database, so removal of it will only restrict my ability to restore from it, not remove data from the current database?

The Server Name is SSEXCH and the directory of the files is called D:\Exchange\Mailbox\First Storage Group\RSG20080627115553

if someone could give me a specific example of the command line I should use to remove these files safely I would appreciate it.

Many thanks for the assistance in advance.

Sorry forgot to mention to get The RSG Datbases and Storage Groups, Run the following Command:

Get-MailboxDatabase ( It will list all your Mailbox Databases Including RSG databases)

To Get StorageGroup, Run this Command:

Get-StorageGroup ( It will list all SG's  including RSG's)

Both get-mailboxdatabase and getstoragegroup both return just the active edb file, not the rsg, i presume based on this I can just delete the files themselves safely?

I presume earlier someone must have removed the rsg, but not the files?
Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

4. Now select the Database that you want to dismount, mark it with V and click on Dismount Selected database:

5. After dismounting the database, you will get a report with a result of the process:

at step 3, I have no manager recovery storage group. This is a title, but the only clickable options are create a RSG.

Under Manage Databases I have analyze log drive space, repair database, show db related event logs, verify database and transaction log files.  The only option that looks close is verify db, but when I click there, the only choice is the First Storage Group.

Seems like the RSG has been removed from here?
All signs show that the RSG has been removed. So you can go ahead and delete the database files. Although I would still love to see the output of this command:

Name                 Server          StorageGroup         Recovery
----                 ------          ------------         --------
Mailbox Database     SSEXCH         First Storage Group  False
OK Now this is conclusive that your RSG is removed. Please delete the Log Files :)
