Laura All good. Working now on the HTC. However, when I sync my XDA (that was working fine when the HTC was not!), it has created random duplicate contacts (931) and appointments (425) in both the PDA and Outlook and I am in the process of fixing this... never ends, eh?

Laura I am declaring this the solution although I will do some more testing over the next week. No more posts from me indicates all is well. The 'missing' contacts and calendar events are now all on the HTC. Thanks for your support and encouragement. Take care.

Laura Hi there! Thanks again for the helpful suggestion. I have already done that so many times I lost count BUT... I have at least found the problem so maybe you can help with the solution :) The problem is caused by contacts or appointments where there are REMARKS IN THE NOTES SECTION ... !! Go figure...
