Change HTTP/1.1 503 Service Unavailable error on Front-end
Posted on 2008-02-08
My Front-End Exchange server never really goes down (it doesn't do anything that would make it), however, occasionally my back-end will go down (patches, hardware issues etc). Although it doesn't happen often, it is inevitable that when it happens, I get the barrage of "did you know that email is down" calls. Primarily, my concern is that when people go to OWA & login, they get re-directed to the HTTP/1.1 503 Service Unavailable error page, which means that FE cannot communicate with the BE. I would like to replace the 503 error page with a custom generated HTM page that has a hyperlink to my IT Systems Status webpage. That way everyone will have the ability to click on the link & see if email is down, if it isn't reported, to report it.
I looked on my FE box & found that the custom errors section doesn't have 503 listed...is that on the back-end Exchange that it is coming from? Or how can I change this?
Hopefully this makes sense. I am on Exchange/Windows 2003.
