My sys-admin colleagues have an Exchange 2003 R2 SP2 server running Outlook Web Access (OWA) through an IIS 6 server (naturally).
OWA seems to crash every couple of weeks. Looking at the Application Pool recycling in IIS, I notice that all of the Recycling options (by time, by number of requests, fixed time etc) are switched off.
Would it be a good idea to switch on Application Pool Recycling (e.g. at 3am every day or something like that) or is recycling the Application Pool not recommended for OWA?
edit: Inconclusive answers so far ... Has anyone else tried this?
