I have had a personal blackberry for some time now and recently had my company add it to their BES. My question is what information is now exchanged between my phone and the company's server exactly? Besides the synchronization of calendar and e-mail, is anything else sent? If I receive personall MMS or SMS messages, are these somehow stored if saved or not saved? Do contacts synchronize? Does any personal data on the phone synchronize like internet usage or personal pictures or any information of the sort? I use my phone for personal reasons, and wanted to make sure that being part of the BES will not interfere. Please advise. Thank you.

depends on the version of the BES and the amount of logging that has been turned on. It's possible to turn on to log virtually everything.."every breath you take, every move you make, I've been watching you"

yes - tasks, notes, contacts., pin to pin messages
Yes it's possible to log SMS, can't say I've every bothered to check what's actually stored.
you mean can they check that you're surfing blackberrypron.com? Then yes they can, you're now accessing internet via the BES in the office.
well erm howabout "Dis-allow 3rd party applications" -not hard for IT to turn on and completely screws you from adding and third party app you might want to install.

If you're that paranoid or got something to hide then why did you get your device added to the BES in the first place...oh and If it was my IT Dept I'd absolutely insist on a complete device wipe if you left...

Remember though that so much gets logged in average IT dept, that they won't look at your data trail as an reason to can you but it'll add to their case if you give them and excuse...

Expertly put! However, it's nice because if you replace your BB all you do is activate again on the BES and all your data comes back. Worth it to me to obey the rules!

For all received and sent messages, it logs the date/timestamp, who (or number) of sender/recipient, the content/body of the message, etc. It is, more or less, a one-to-one synchronization of the user database for SMS messages to a CSV file on the BES. I do not believe that MMS messages are logged, to be perfectly honest - perhaps that was fixed with the latest release.

I have created an 'Unplugged' policy that is the least restrictive policy possible (Default and then some). This is for my users who decide to leave the company or just the BES and want all of their functionality returned to the device. I've had 1 user opt to enroll in the policy, thus far. We also require a wipe of the device, although enforcing that on a user who turns off their device, changes their number, etc., is kind of hard to compete with.
