XTNDConnect crashes (T630)

Since adding a few recurring entries in my Outlook calendar XTNDConnect now
crashes with monotonus regularity (I connect via a USB cable).

One thing that may be the cause of the problem lies in the box that pops up
immedately after connecting the phone 'Allow access to Outlook for 'x'
minutes'. I was always able to change this ans selected the maximum (10
minutes) but for some reason it automatically selects one minute now and my
feeling is that this timescale is not long enough for the synch process to
fully complete - hence the crash.

Is there a way of changing this process?

Many thanks
