I have 1000+ contacts to synchronise and a good number of calendar / task entries. Synchronisation worked OK with my original 9210 but sometime after that it became virtually impossible to get any my Communicators to sync with MS Outlook. Each time a new version of PC Suite was released I tried again with only very occasional and temporary success. Posts in this forum suggested that a lot of people were having similar issues.
PC Suite v6.7 has been released (see AAS News) so I installed it on my laptop without any great expectation. To my delight, it worked like a dream so I repeated the exercise on my home desktop and that worked as well.
I have only two data points so far but the prognosis seems better than it has been for a long time. For those out there who have been having similar problems an upgrade to v6.7 seems woth a try. Here's hoping that Nokia have finally sorted it 😊
For reference, I have Windows XP Professional +SP2, Outlook 2002 and the 9500 is v5.22
