One of the readers sent us a question about data migration. He uses two email clients: Mac Mail (default client on Mac) and Mac Outlook (a client by Microsoft). This person requires migrating data across both of the clients at times. He also has to send Mac Outlook data to users without Outlook installed but Mac Mail. So, he has to either forward a large database, which takes time, or convert the files for Mac Mail.
So, if you are in the same situation, this article applies to you.
Mac Mail and Outlook Mac
Mac Mail and Mac Outlook work in the same platform – Mac OS, and yet, transferring data to-and-forth can be too much of a hassle.
The reason: Mac Mail does not export data to OLM and Mac Outlook can only import OLM and PST. And, Mac Outlook can only export data to OLM, while Mac Mail can only import in MBOX.
The lack of a data file that is compatible with both clients can be difficult challenge to overcome.
Here is something that is easy to work with and offer a safe way to move data across these clients.
