Mutt is a robust email application designed for Unix-like systems. This program was initially built as a Mail User Agent, but evolved to be a mail client having abundance of built-in commands and directives over the years. Mutt provides you with myriad advanced capabilities, including message threading, support for mailing lists, multiple message tagging, etc. The email client supports a range of mail storing formats, such as MBOX and Maildir.

Mutt stores email messages in folders. The default location of the inbox folder is the $MAIL shell variable. At startup, the mails are shown in the spoolfile at "/var/spool/mail/USER". The mails that have been read can be moved to the 'mbox' folder by setting the variable 'move=yes'. Mutt can work with four different mailbox formats: MBOX, MAILDIR, MH, and MMDF. You can specify the format to be used in mbox_type.

If you are looking for a migration to Windows and would like to try using MS Outlook, then you need to move all your mails out of Mutt to the Outlook data files.
