Time out issue with OWA. Users are being prompt to enter their credentials within five minutes of using OWA.
OWA repeated authentication problem, IE 8, Exchange 2003
Users are prompted for authentication in OWA within unreasonable amount of time-less than 3 minutes. For example, when they go to OWA url, then enter their credentials, then when they click on the email, they have to enter their credentials again. After several minutes whether they are just clicking on the email or writing an email, the session ends and they have to enter their user name and password again.
After troubleshooting all day and asking users questions. It looks like the issue is not only restricted to IE8 but happens in all browsers (I have been told so, but will be verifying today the problem across al browsers). Furthermore, it looks like the authentication prompt is due to some kind of a time out settings because the OWA session times out after several minutes. What I mean is that when I enter the credentials, it will not asks me for authentication right away; I can click and open emails without a prompt, but after several minutes passed by, I am prompted to enter the credentials again. Also, if someone writes an email longer than 2-3 minutes, they would have to re enter their credentials over agian.
It looks like the session is timing out within reasonable time.
