[Ham-Computers] Keeping two email PST files in sync

[J. Gordon Beattie, Jr., W2TTT]

Hi All,
I have two laptop computers and would like to keep their Outlook PST files
in sync.
I can use multiple email accounts to copy email between them, but I have not
figured out a rule to do that.
Any ideas on how one can do this?
I'm trying to avoid the very slow backup restore process by doing this as
messages come in.
