Hi, we run a BES in conjunction with our Exchange 2007 SP1 server. Most users are inside the corporate network, and are connecting to exchange in the traditional sense. A number of us have Blackberry's, and we have no issues. However, there is one user who is having a problem. He works outside the office and connects his Outlook to exchange via POP3. In the past he has gotten all his appointments and contacts sync'd between Outlook and the Blackberry. (ie: he puts an appt in outlook, it shows up in the BB, and vice versa). However, now this syncronization has been lost. His OWA still updates and sync's correctly, however the contacts and appts are not sync'd between outlook and the BB. Nothing has changed in our BES or Exchange server recently, so I'm at a loss as to why it would have changed. Can anyone give some suggestions as to how we could get this functionality back for him? Thanks.
