We have an iMAC for a home computer and both of us have a MacBook Air. We decided to use MAC Mail for the primary e-mail over Outlook for MAC. In the PC world, you are able to create a .pst file on Outlook that is where all your e-mail is saved too when you check your mail. In turn, you are able to link that .pst file amongst other computers on your network and see all your e-mail from any computer. (The only limitation with that setup is that only one computer at a time can have that file open) We are looking to do a similar setup with the MACS and are new to the MAC/OS X world. Can someone tell me how this is done?
