OWA: The specified request cannot be executed from current Application Pool
I just spent an hour Googling and hammering away at our Exchange 2003 server to find out why some users suddenly started getting the error “The specified request cannot be executed from current Application Pool” when they attempted to log into OWA (Outlook Web Access).
These users never log into an actual workstation anywhere so I figured that if I did that for them and launched an actual Outlook 2003 session, maybe I would get an error that would lead me in the right direction.
I was greeted with a prompt to change their password because their Active Directory password has expired. Bingo! I changed their password and the error went away.
I thought that I’d share this here because Google doesn’t return any other sites that have this tip when you search for the error.
