Exchange 2000 "not enough memory" event ID 12800

We have Exchange 2000 running on Windows 2000, service pack 4, and Office 2003.

When one user (and it seems only one user) uses Outlook in "Cached Exchange Mode" he is unable to sync correctly, and the following messages are recorded.
I've used several client machines, with different profiles, but the problem always occurs; so I think it's a problem with the server.
Before someone points out that the server is running low on memory, it has 1GB and has plenty unallocated.

This is recorded in the server's event log

I've tried the usual google answers, any bright ideas?

Do you see Event ID- 9582 also in your Application log? If yes, its Virtual Memory Fragmentation issue, check the KB - 325044 for more help.
Is this happening only when this particular user try to sync with Exchange server?
Also match the file versions given in this article with the file versions on your exchange box. This hotfix might solve your problem.

There are no 9582 messages.

It is indeed (so far as we can tell) one user, and only when trying to sync.

MS are sending me the hotfix. If that doesn't work I'll work my way through the KB's.

Thanks for the help chaps,

Phil.
