The Windows 10 Mail app is similar to previous apps in terms of user experience, however there is a number of forensic differences. The main one is the way in which emails are stored. They are no longer saved as .eml files; rather, they are now saved as HTML or .txt files.
Another neat feature in the new Mail app is the ability to connect to multiple accounts. Much like Gmail, Mail now comes with the ability to switch between different accounts - and users can now add other email providers such as Gmail and Yahoo to their Microsoft Mail apps.
