We are using Exchange 2003 Enterprise on a member server. Currently we have a single mail store. The Priv1 and Pub1 are approximately 28 gigs combined at the present time. We recently configured RPC/HTTP (Thank You Simon) and are in the process of rolling it out to outside branches. I know that this is going to cause our mail store to grow. We have approximate 125 users in our outer branches and presently they are using up very little space. At what point would it be prudent to create a second store on the same server, move users mailboxes, and the best approach of doing so. We have around 230 gigs free on the server so space is not a concern (yet). Is it better to leave it in one larger store or split it up for maintenance reasons, if one store was corrupt it would only take down a portion of the company during a repair. Or would the Exchange Server be a little more finicky with multiple stores.
Any comments would be greatly appreciated.
