In the latest build 0146 and the last two builds before it (and possibly earlier builds but we didn't notice it) there appears to be an issue with the proper synchronisation of Groupwise Folders

We regularly find mail items appearing in the 'Inbox' folder on the device, when Groupwise rules moved the mail on Delivery to another folder (eg. 'Patch Announcements').

It is not necessarily consistent - not ALL mail items are appearing in the Device Inbox folder, some of the items show properly in the expected folders, but it is significant enough that the issue is noticeable to users and confusing.

On a positive note - Datasync does appear to correctly keep the object in sync even when in the wrong place - for example, reading the item in its correct folder in Groupwise will mark the mail as read in the incorrect Inbox folder on the Device...
