Office 2008 with 10.5 – Can’t Resave/Save

I know this is an ongoing problem, but I'm having some really strange problems... My users are able to save a document, but after making further changes, they can't resave. I've found lots of documentation on this issue for 10.4 (http://word.mvps.org/Mac/CantSaveToServer.html) I've tried Symlinking the .TemporaryItems folder to their ~/Library/Caches folder, etc. and I can't get it going. The strangest thing, is that I just upgraded from 10.4 server with 10.5 clients, and it was all working perfectly, until everyone came back this morning, and it apparently didn't work at all.. Other articles that I've been through: http://www.tech-archive.net/Archive/Mac/microsoft.public.mac.office.word/2008-08/msg00970.html http://www.macosxhints.com/article.php?story=2001110610290643 Any help is greatly appreciated =) Thank you!
