You can drag the Outlook folders to the desktop and the emails will turn to Mbox, but it is very slow, inaccurate, and tedious. Although, there are few manual ways to make the switch, but those often times don’t work the way one wants them to. The conversion for Outlook 2011 to Apple Mail is also one such task that can be very difficult. There are no official tools or methods that users can employ for their email migration needs. However, the solution to make the transfer of data from one to another is still surprisingly very hard to find. You don’t like an email client, you simply switch to another one.
The email migration is very common these days.
