[OGo-Outlook] endless propfind

[Peter Duda]

Anyone know why one of my outlook clients would be sending an endless stream
of PROPFIND to the ZideStore out log?

I get about 25,000 of these for this one user in a 12 hour period - just a
constant stream - 1 per second
Seems like a problem on the client side, but I don't know what a propfind is
or what could be causing it.

Thanks
