 Exchange Best Practices
Can anyone tell me what the best practice is for the number of information stores that can be on one Exchange 2003 Server. I have one information store at this time, but would like to split it into different stores depending on the location since our company has grown and has offices throughout the US. Our mailbox size has increased from 500 mailboxes to over 800 mailboxes and we expect continued growth so I do not feel comfortable keeping everyone in one information store since it is critical that I keep everyone up and running at all times. Any information will be greatly appreciated.

Answer Wiki:
As long as you have all the Service packs and updates having multiple stores is probably your best option. Although with so many users I am not sure why you don't have multiple Exchange Servers. By Microsoft?s own admission they say that having 2 to 3 stores is best. The more information and mailboxes you have in one store the more potential for problems. Especially if many of the mailboxes are over 2GB. I keep all my users under 2 Gig and I split my company in half and have two stores. I have the OS running on two Mirrored drives and I have all the Exchange stores loaded on a RAID 5 partition.
