NAC - looking for Destop and Project Management Software

[Ben Swann]

No Audi Content here, but as great minds on the list ..did some searching on this, but got bombed by too many pop ups and figured someone has recommendation..

I'm looking for a Windows XP Compatable Desktop Organizer/integration program that integrates/coordinates Mail, Calender, Task/Project management, Billing Program  with file links.  Any ideas?  Sort of what one would expect Microsoft Outlook to do.  Of course I don't want to pay a lot - freeware is good.  If it does more, I'll pay more type of thing.  Trying to coordinate the myriad of interrelated tasks that tend to get overwhelming.
