Software to replayce Schesdule 7 for 95

Hi all...

I am a network Administrator for a small company (50 users). They currently use Schesdule Plus which works great but only if you have Office 97 installed. I tried upgrading to 2003 but then Schesdule Plus stops working. I need a software that has the same capabilities if not more as Schesdule Plus. My users need to see the schesdule over the network and be able to add event, reminder and such. What would be a good software that does this and more? Please let me know since it's vital that I get this to them!

Thanks

The software is called Schedule Plus not Schesdule Plus

And on their site there's a link to support Excel version 2002 or 2003:
