[DICKO]

My Managing Director (it's always the high up guys, isn't it) is having some issues where he puts an appointment in to his BB (Curve 8310 btw) and it SOMETIMES disappears from his outlook after it's been entered.

Honestly, I don't even know where to start diagnosing this problem. I have 25 other users (including myself) who are having no issues whatsoever.

We are running BES 4.1.6 attached to Exchange 2003 and his client is Outlook 2007, although he's only recently been migrated to a new machine and his previous version (2003) also had the same issue. So it's not PC related.

The only difference that I can see between him and anyone else is that his Assistant sometimes sets up appointments for him, but never responds to other peoples requests (since she wants him to make the decision about attending).

Any advice for how to go about working out what's going on?
