Hi, all-- We're running Exchange 2003 on Windows 2003, with BlackBerry Enterprise Server's free (up to 15 clients) version 4.1.4.15 (we only have one BlackBerry unit to support). For about the past 3-4 weeks, we have experienced slowdowns in mail delivery and in client response time whenever our single BlackBerry user synchronizes. Today, the server was completely disabled. We think it might be related to the SMTP connector, as while the problem persisted, we couldn't even drill down to it in Exchange System Manager. Turning off all the BlackBerry services and rebooting the server solved the problem. Has anyone else had issues with BlackBerry Enterprise Server (particularly the free version) and Exchange Server 2003, especially with the SMTP connector? Thanks! --Bill. -- Bill Wheeler, Systems Administration Michigan State University Libraries [log in to unmask] (517) 432-6123 x 234
