Having upgraded to my fourth BB I was surprised to find that 4.1 would not would pick up my outlook pab folder and clicking on the browse button would simply give an hour glass for 5 seconds and then fail.

Thanks to really nice helpful and professional young lady called Asma on the Data Support with O2 its now working.

Have a look here, because I could not post a URL please add the usuall blackberry.com/ then add /knowledgecenterpublic/livelink.exe/fetch/2000/8021/7919/8125/Support_-_MS_Outlook_is_missing,_invalid_or_points_to_a_fil e_of_zero_length.html?nodeid=154079&vernum=10

I think this will get around the link issue ;-0

Best wishes and thanks for this forum, it's a great facility.
Kind regards
