One of my clients is having some synchronisation issues with their BlackBerries. They're running BES 4.1.3 on Windows SBS 2003. There are 5 BlackBerry users.
Email itself is working fine for all 5 but at least 3 of them are not able to sync their calendar, contacts or tasks. In the properties of all BB users, under PIM Sync, all "synchronization enabled" fields are "true", and the handsets have wireless synchronization turned on as well.
I have talked one user through wiping and reactivating his device but it made no difference.
I have access to the server but can't go on-site to see the handsets until Wednesday. I spoke to someone at Telstra's wireless data support on Friday but at that stage the client had told me that everyone could sync except for one user, so the support rep told me it would likely be a problem with the handset. Since I later found out it was affecting more than one user I suspect the problem is on the server. I believe some users have BlackBerry Desktop Manager installed but I don't know anything about it, could that be affecting it somehow?
Can anyone give me some ideas on where to start looking into this?
