A/S at work= no problems
A/S at home= duplicates all entries in my contacts list, you know how long it takes to delete them one by one

Any idea why this is happening?

Have you checked to see if the contacts are actually duplicated within Outlook on your home PC? I've seen this happen many times for no known reason. If this is the case you can use a plug-in to Outlook to remove the duplicates, there is a trial located here:

hadn't thought of that will check it out. I don't recall seeing dups there but will double check. Thanks for the link.

When you sync at home and it duplicates the files, if you sync again does it create more duplicates? If not, maybe there is a difference and your best bet would be to delete the contacts on the home computer and just use the ones from the office. Backup all data first of course.

I've had this occur on my PPC in the past, but for calendar entries - I resolved it by deleting the duplicates (that took a while ), then deleting & recreating my A/S partnership.

SKTools includes a utility that very quickly finds duplicate contacts and you can delete them - this may speed things up a bit for you:
