Bug? - Outlook Task Synchronization

[Quantum7]

I'm testing out this feature + Outlook task synchronization in 3.5d.

The Help file says the "Flag" attribute from UR is synchronized with the "Status" attribute in Outlook. However, if I flag an attribute in UR as "Completed", the status in Outlook doesn't go to "Completed".

This means it isn't possible to flag a task in UR as complete. I have to do it in Outlook.

Anything I'm missing?
