Have a law firm client. They have every email since the dawn of time. Total database size for 42 users is just over 130gb. There are multiple users with mailboxes in excess of 20gb. Some of these users open other users mailboxes that are in excess of 20gb....so the local OST can reach 50gb+. It has gotten to a point where I cannot throw anymore horsepower or RAM at the server to increase speed. I figure I need to look into some sort of archiving.
The only real requirement is that EVERYTHING must be SEARCHABLE! I cannot stress this enough. I think they spend more time searching their emails than anything else.
I am curious what will happen to local cache files should some sort of archiving policy be put into place. Will the OST shrink? Will they have access to archive items if they are totally offline? Can I roll this out for a few beta test users?
They do have Exchange Enterprise licenses and everyone is on Outlook 2010. There is ample space left on the server should I need to set up another mailbox store or whatever. I would like to have a plan of attack. Any input is greatly appreciated!
