I am still waiting to find out what BES version we are on and exchange as well.
I see what you are saying about the communication between the mailbox and the BES and it makes sense. Now my problem is that if I delete an email from my outlook inbox, wait 5-15 minutes it will eventually get removed from my 8830. However, if one of my mailbox rules comes into play and moves an email from my inbox to a personal folder (pst) this is never reflected on the 8830, even after waiting 24 hours
Is this the nature of the beast or could it still be a setting or an update that needs to happen?
