Blackberry deletes messages after 30 days
 

I have a Blackberry 8700 that keeps deleting messages after 30 days even though my message options are set to keep message forever. I have changed this setting twice and still end up with the same result. The BB is connected to a BES. :-o

It may be an IT policy. If it is, you can look here to find out how to remove it: Remove IT Policy - BlackBerryFAQ

Sounds good let me check with the BES admin.

if you are on a BES it's likely a corporate policy to keep messages for only 30 days, do not try to remove the IT policy from the device if you are on a BES.

The *only* way to get that changed is to talk to your BES admin, and see if it is possible.
