I'm using a Windows Mobile 6.1 Professional device to synchronize my Outlook 2007 data at home with the Exchange Server (via Direct Push) and my Outlook data in the office using ActiveSync 4.5.
Now, whenever I change a contact or task at one of the three possible places (home, phone, office), a random number of contacts or tasks is being duplicated.
What is the root cause for this problem and what can I do to work around it or avoid it altogether?
