Minor FYI - an error message isn't matching the normal log; perhaps it should read "Some non-critical events (e.g. rescheduling notices) were skipped during the last synchronization"
Did a clean install of 2.0.1.7, performed an initial sync, and received a message "Some documents were skipped during last synchronization.  Please see s...
I believe it is referring to items such as "2010-05-04 14:36:46,899 [6] WARN  - Child document is not processed since it doesn't have CalendarDateTime field: D881AD73F4723E42852576710083CB3A".
This may be a confusing error message to the users, if the documents that are being skipped definitely don't affect the schedule.  Is there any way to tell and adjust the text in the error message to indicate whether the two calendars will be 100% accurate or not? 
Two possible different levels of notes (please re-write - I did not give these much review)

1. [Example #1] IMPORTANT:  some events within the specified timeperiod were not synchronized and may appear in one calendar but not the other.  Please see your log for details.
2. [Example #2] Note:  some minor events were not synchronized - your calendars should still match

Thanks,
