Re: Outlook 2003 Synchronization
I'm not aware of anything other than what was mentioned with the PST file. AFAIK, Micosoft's solution would be to get Exchange server.
I don't know how you feel about web based email, but I have several pop accounts that are personal accounts and I have all of them forwarded to my Gmail which I access from both my desktop and laptop. When I send from my Gmail, I can set the "From:" to any of my accounts, even my work address.
For my work email I just use Thunderbird on my laptop. I will also occasionally access my work email through our webmail but it only shows new messages that haven't been downloaded to my laptop.
