Question : Exchange-Outlook Synchronization Log mssgs

I have one user who is getting Synchronization Log messages in her Outlook every few minutes.  Her email seems to be coming and going okay, but I'm concerned that something may not be quite right.  We have Exchange 2000 on a Windows Server 2000 box and the user is running Outlook 2003 as part of Office 2003 Pro.  I can't seem to find anything useful about how to address this.  Any ideas?

Here's the exact text (with the user's name removed):
17:25:40 Synchronizer Version 11.0.8200
17:25:40 Synchronizing Mailbox 'username'
17:25:40 Synchronizing Hierarchy
17:25:40 Done
17:25:41 Microsoft Exchange offline address book
17:25:41       0X80070002
