Mac Mail to Thunderbird Migration – What to Do and What to Avoid!

The article is for Mac Mail to Thunderbird Migration and what to do and what not to do. Read full article for details.

Mac Mail to Thunderbird Migration

Changing the email clients can often turn out to be a harder job than what you might have anticipated at first. Clearly, just switching to a different client isn’t complicated. You just install the client you want to use and start using it. And today’s applications are much better in creating user friendly interfaces that getting comfortable with a new program won’t take too long.

It’s the migration of data that makes the entire enterprise intimidating for both beginners and experts. The migration of emails from Mac Mail to Thunderbird cannot be done simply through in-built features or straightforward methods. The difference in data files and how the data is structured in both clients is vastly dissimilar. It’s not a matter of simply copying and pasting or using the import/export function of either client.

Mac Mail Doesn’t Use MBOX file

Since Thunderbird uses MBOX file in variety of situations, most users are under the assumption that they can use the MBOX files from Mac Mail to migrate the data. Unfortunately, Mac Mail doesn’t use the standard MBOX file anymore (it was just in the very first edition).

The misconception arises from the slightly different use of MBOX in Mac Mail. If you will take a look at your profile database folder (also called identity database), you will notice files with .mbox extension. But on a closer look, they are not standard MBOX files but rather file packages with .mbox extension that act more or less like folders that you can simply open to view the contents. And the actual content (emails) are stored in EMLX files. A single EMLX file contains a single email message and the attachments are stored in EMLXPART files.

Manual Methods Don’t Hold Up Against Large Sized Databases and Complex items!

There are few manual methods to migrate data across both these clients. There’s also a way to archive your data to MBOX files form Mac Mail folders. But these manual methods can take painfully long hours and yet not produce accurate and fruitful results.

Any manual technique where you have to do everything manually specially misses the mark when it comes to large database from Mac Mail or those databases that contain complex items like UNICODE content or MIME defined content. In those cases, what you can end up with if you don’t have proper set of tools is data integrity loss. Many recommended manual solutions take a nose-dive at the slightest hint of data components that aren’t simple.
