It might have something to do with a fairly recent bug that cropped up with Outlook 2003 and rules contained therein. Apparently, if a rule in Outlook points to a folder that no longer exists, it can stop the 5.5 message store service. Do a search in the knowledge base: there is a hotfix for Exchange that cures the problem. -----Original Message----- From: sime.vuksanovic@xxxxxxxxxxxxxxx [mailto:sime.vuksanovic@xxxxxxxxxxxxxxx] Sent: Sunday, July 04, 2004 11:35 AM To: [ExchangeList] Subject: [exchangelist] Information store stops unexpectedly http://www.MSExchange.org/ I have Windows NT 4.0 SP6 it is PDC and Exchange Server 5.5 SP4 and ScanMail V 3.51.
