checking email on multiple computers

[Guest]

As i check my email on multiple computers (my desktop & tablet pc) during the
day, how can i see all my emails not just the new ones since i last checked
my email?

Set one or both computers to have the accts "leave a copy of mail on server"
and remove after xx days so the server doesn't get clogged.
Tools>options>accts>advanced.
