Before a person can move files from Mozilla Thunderbird MSF to Outlook, they need to know which file formats each platform supports. When a person wants to switch from one email client to another, the file formats that are used to store data are the most important things to think about. People who use an email app that saves files in MBOX or MSF formats and want to switch to Outlook will need to convert their files from MBOX or MSF to PST.

About the PST format

Personal Storage Table is what PST stands for. These files in the personal folder are from Outlook. These files store the information in a user's mailbox account. They hold email folders and other things like contacts, attachments, meetings, and more.

About the MSF format

Mail Summary File is what MSF stands for. The main thing that these MSF files have to do with Mozilla Thunderbird This email software saves the contents of each mailbox folder in two different types of files:
Files that don't have an ending are MBOX files, which are used to store email. Even though these files don't have an extension, they are actually MBOX files that hold email messages and are used by the Mozilla Thunderbird email app as a mailbox folder.
Files ending in.msf are index.msf files, also known as Mail-Summary Files that are linked to each mailing folder in Mozilla Thunderbird's profile. They hold message summaries of the emails that are stored in their associated MBOX files.

Why Should I Export Thunderbird MSF to PST?

This is one of the most popular email clients. It saves users' emails and personal email data in personal folders, which are files with the PST file format, which stands for "Personal Storage Table."

To be exact, Mozilla Thunderbird doesn't have any control tools for personal data storage. As a result, Thunderbird cannot be used as a full desktop email management tool. Outlook, on the other hand, has everything you need to handle your emails from start to finish. This is the reason why a lot of people are looking for the switchover and want to export MSF to PST.
