I think this is the most appropriate forum, but will be happy to be corrected.

A secretary spent a number of hours on Monday filing about 550 emails in the manager's mailbox and noticed by the end of Tuesday the majority (probably 400) had returned to the inbox.

This looks a lot like the problem in TID7007372 and Blackberry KB24634.

Our BES is version 4.1.7 and the Groupwise client on the BES is GW 8.02 HP2. The users GW client is 8.02 HP3 and the POA is GW 8.02 HP3 so it seems the problem should no longer occur.

Any clues how we can troubleshoot this?
