I am using outlook web access to access work (exchange) email. It's set up as a normal email account via BIS. Normally I would get the above message when my password expires. I would go into BIS and change it and it would work again.

As of today, I am getting this message randomly every few hours. I don't have to change the password to fix it, i just need to login to bis and re-validate the account. After that it pulls my work email and seems to work for a few hours before doing this again.

A friend of mine has been having this problem for about a month now, while i just started having it today..

Any ideas? This sucks!

I'm experiencing the same thing. Every day I have to re-validate. It's annoying. Possibly this happens when your email server goes down and the Blackberry can't communicate with it...
