pop3

[Ela]

After selecting pop3, all mails will be pulled down to a local computer. How
and where can I retrieve the archive and so later I can load it back to a
new computer? This feature is important because so I can keep track of all
past emails even after formating the machine and so.

Outlook stores all data in its folders in a single file - select File, Data
File Management to see the location and name of this file.
