We are currently in the process of migrating user mailboxes to multiple stores to aid in doing restores and such. Our current setup is that we have 3 mail stores, one well over 100GB edb+stm, which makes it very difficult to do restores. We have setup 5 new stores that will help balance out our mailboxes and make the restores much easier. My question is that we are not planning on using the 3 old stores once we are done but we don't know if we will need them for restores from the past. Can we delete these stores and just restore to the Recovery Storage Group or do the old stores need to be present? We are VERY vigilant with our backups as our industry is prone to legal issues and such that require us to restore mailboxes to a specific date. I have moved all of the mailboxes out of one of the stores, except the 2 system boxes, and need to know if I should just run an eseutil.exe /d to shrink it or just completely delete the mail store? We use Veritas for backups if that info is needed.
Any assistance would help..
