I had a problem synching my 700p to Outlook - it always hung transfering my calendar. After trying everything I could find in every forum I finally got it to work so I thought I'd post what my solution was.

The error in the HotSync log was:

OLERR:03-0023
OLERR:11-000A
OLERR:0D-000E
OLERR:0D-0004
OLERR:0D-0001
-Recovery Sync
Outlook Calendar synchronization failed

After beating my head trying other "fixes" I found a couple of calendar entries that spanned two days. Once I deleted these everything works peachy!

I hope this helps.
