Express time out errors on Windows 2003 End users complain that Express times out when they are in the middle of composing a message, and they lose the content of their message. If Express is running on a Windows 2003 server this will occur if the Windows 2003 Connection Timeout setting has not been changed from the default 120 seconds. This document explains how to address this issue. In Windows Server 2003, the default web site Connection Timeout setting is 120 seconds. This will overrule the Express time out settings in MailSite, which is set to a default of 1200 seconds. To change the web site Connection Timeout setting in Windows Server 2003: 1. Open the IIS Manager (Control Panel -> Administrative Tools -> IIS Manager) 2. Open up your web server tree and go to the "Web Sites" Properties dialog box. 3. Change the "Connection Timeout" setting to equal the time out settings in MailSite Express - the default is 1200 seconds. This should allow your users to be write e-mails for 20 minutes without needing to log in again. To change the time out settings in MailSite Express: 1. Open the "expresscfg.asp" file in the \MailSite\Express\Web directory on your server 2. Set the "intSessionLength" value to the number of minutes of inactivity you require before timing out an Express session (the default is 20).
