I would assume for performance reasons, you would want to set a limit on the number of people in each mailbox store...a server can only handle so much traffic. Doesn't mean you can't add servers/stores/storage groups etc... Devin -----Original Message----- From: Douglas M. Long [mailto:admindoug@xxxxxxxxx] Sent: Thursday, February 02, 2006 8:18 AM To: [ExchangeList] Subject: [exchangelist] Information store limit http://www.MSExchange.org/ I was talking to someone today and they said that real world experience says that you shouldn't have more than 250 users in an information store (Exchange 2003) for performance reasons. I have been under the assumption that the only real limits were purely based of the particular scenario (such as disaster recovery expectations, disk IO, number of items in mailboxes, etc). So, is there any validity to the statement, or is it more scenario based? What about with Exchange 2000? ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp ------------------------------------------------------ Visit TechGenix.com for more information about our other sites: http://www.techgenix.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: devin@xxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to info@xxxxxxxxxxxxxx
