...and the people in the office are not too pleased with that.  Or you have a PalmPre that won't work with the password policy - http://geekswithblogs.net/ntpro/archive/2009/06/25/133047.aspx

To edit this launch the Exchange 2007 console, click on the organization configuration, then on client access.  Right mouse click on the "Windows SBS Mobile Mailbox policy".  Click on the password tab and uncheck the "require password".

Sync the phones again, and you'll be good to go.

Here's the bad news... you just disabled that on EVERYONE and you probably don't want to do that in all cases. 

So here's a compromise.  Set up a brand NEW policy that copies over all of the settings of the SBS default policy, this time unchecking that password box.

Then you go down in the console to the recipient configuration, click on Mailbox and go into the properties of the user you want to exclude from the passwords on the mobile devices.
