Recently our Exchange 2003 SP2 server experienced a problem where users reported they could not connect using their mobile devices (iPhones) or webmail. Logging on to the Exchange Server revealed that the Information Store had stopped and the Application Event logs were filled with thousands of ActiveSync errors. In addition, the current W3SVC1 log file was 2.5 gigs. A restart of the Exchange server brought it back up and it has been working fine since. In fact we have never had the Information Store stop like this before in 4 years of uptime. Does anybody have some insight why this might have occured ? We are wondering if the introduction of more activesync mobile devices in the last year might have caused the problem. Single Exchange Server 2003 SP2 - Single storage group with appox 400 mailbox's. User clients are Outlook 2003, Entourage 2008, 40 iPhone/windows mobile devices.

That log file grew to 2.5GB? What's the recycle time on that? Daily, Weekly, Monthly, size? "jmpr1" wrote in message news:ef49c244-5f90-4528-8913-f8e9b6087c09...

A new W3SVC1 log file is created for each day at 8:00 pm - so I end up with many log files after a period of time. The format for today's file is ex100512.log for instance. The SMTPSVC1 log files do the same - a log file for each day. The normal size for one of the W3SVC1 logs is 80 - 100 Megs, NOT 2.5 Gigs.
