thunderbird message storage type to outlook

Most Thunderbird users are unfamiliar with the term Message Storage Type. It wasn’t the case in earlier versions of Thunderbird, in which you could change the message store type at will. But in the modern Thunderbird client, this particular setting is greyed out. That is to say, it’s no longer functional. But in reality, it’s just hidden.

Anyhow, our main goal in this article is to help two types of users. One who are looking to change the Message store type in Thunderbird. And the other who wish to import Thunderbird message storage type to Outlook. But, first let us take a look at the different formats that Thunderbird uses for message storage.

Thunderbird Message Storage Types

There are only two kinds of file formats that Thunderbird uses to store its messages. For new Thunderbird users, they only know about the default format. The two storage types are:

MBOX – It is termed as the most common format to use for storing emails. It stores multiple email messages in a single mailbox file. Thunderbird MBOX file has no extension. That is to say, Thunderbird uses files having no extension but with same name as the mailbox folder for storing emails. Eg – Inbox, Sent, etc.

Maildir – It is an old format that stores each email message in a separate file. Thunderbird maildir files are different from general maildir files as it has no email flags in it. It holds only one message per file.
