Share PST file across multiple machines

Share PST file across multiple machines

Does anyone have experience sharing one .pst file across multiple Outlook installations? I want to have one calendar, contacts, etc on multiple machines. I have several ways to get the file on the machines (VPN windows share, Mesh, etc) but I don't know whether outlook will freak out if another program is modifying the data file or if I'm going to run into problems if both are running at the same time, etc.
