We are using Offline Folders feature of Windows Vista to make files on network shares available when out of office. Mostly it is working, but every time I do a sync I get a lot of such errors:

D500E7B8.tmp - A file was deleted on this computer and changed on the server while this computer was offline.

There are hundreds of them. I always select all of them and choose resolution "Delete from both locations". But what is causing this and how can I avoid it?

I suspect the reason is that we are using Debian and Samba (3.4.7) on our file server. I've been looking for some Samba options that would cure this, but with no success. I learned that probably the cause is, that both Word and Excel are using specific pattern to change files - they never change the original file, but instead always write a new temporary file and rename it to original file, when you click Save.
