Resolution

There are tasks in Microsoft Outlook with conflict icon. To find all of them please sort the list by the icon.

You need to resolve the conflicts. Just open a conflicted task:

You need to accept changes or throw them away.

Then, synchronization will work correctly, if there is no other conflict.
