Outlook 2000 Net Folder Updates fail

I run a network of 12 PCs varying with 95 and 98 connected to an NT4 Server with exchange 5.5 SP3 all PCs have the Outlook 2000 mail client and share a folder using net folder from one users PC this all works fine except for one fact the updates to the net folders have to be manually processed by the recipient hence making the point of net folders not functional. I have tried everything i can think of along with all the suggestions off the Knowledge Base, i have recreated the net folders removed and re-installed both the whole of Office 2000 and Outlook 2000 and removed it using the Eraser2k.exe package and seem to be at a loss
