Hotsync errors with Treo

[Bob]

I have successfully used HotSync with my Treo 650 since January. After
successful syncs this morning, I started getting the error messages below.
I did a soft reset on the Treo and rebooted my computer, with no success.
There is no reported problem with the company's Exchange Server. I'm
syncing via a cradle and USB cable. Because the only errors are with
Outlook, I'm trying to find out what to do from an Outlook standpoint.
Outlook itself seems to be working fine; it is Outlook 2003 SP2. The
HotSync conduits seem fine, and all non-outlook parts of the sync seem to be
working (as per the log below) Any ideas?

Here is the HotSync log:
