SYMPTOMS

CAUSE

When using Windows 2003, the Application Recycling time for COM+ could be causing IIS to lose its Session State within web mail.

RESOLUTION

To verify whether this is the issue, open the Internet Service Manager under the Administrative Tools program group. Under Application Pools, a list of named application pools should appear.

MailEnable will run the web mail application under the application pool called MailEnableAppPool. By selecting this Application Pool, it should list MEWebMail (and others) underneath it.

Right clicking on this application pool and selecting Properties, will display whether the application pool is to be recycled (and if so, after so many minutes). The default value for this number should be 1740. This default value can be increased to reduce the incidence of session state loss.
