Password unlock?

[tripflex]

I currently use my work exchange server to hold all my emails and contacts...but my sever requires that i have a password on my mogul.

Just wondering if anybody knows how to get around this and disable it? I hate having to type in a password every 15 minutes whenever i want to look at my phone...such a pain! I would much rather just have it whenever the phone starts...or maybe even like every 2 hours or so...not 15 minutes!!

Please helppppp!!!!

Thanks!
