Convert Mozilla Thunderbird MSF to PST
For transferring data from Mozilla Thunderbird MSF to Outlook; first of all what a user needs to understand, is the file formats that are being supported by these respective mailing platforms. The file formats in which data is stored happen to the most primary concerns while any user initiates any type of conversion from 1 particular email client to some other. If a user is using some email client that uses MBOX or MSF file formats and wish to make a switch over to Outlook, then MBOX / MSF to PST conversion is needed.
About PST Format
PST stands for Personal Storage Table. These personal folder files belong to Outlook. These data files store users’ mailbox account’s data consisting of email folders along with other items, like contacts, attachments, appointments, and much more.
About MSF Format
MSF stands for Mail Summary File. These MSF files are principally linked with Mozilla Thunderbird This email client stores content of every mailbox folder in 2 file types, as follows:
- Files with no extension: These are mail-storage files that have MBOX format. Though these files are created without any extension they are MBOX files consisting of email messages that represent a mailbox folder in Mozilla Thunderbird email client.
- Files with .msf extension: These are index MSF files or the Mail-Summary Files that are assigned to every mailing folder in Mozilla Thunderbird’s profile containing message summaries of those emails that are stored inside their corresponding MBOX files.
Why Export Thunderbird MSF to PST?
Microsoft Outlook email application is one of the most popular email clients that stores users’ emails as well as personal email data in personal folders i.e. the files with PST file format or Personal Storage Table. Even though Mozilla Thunderbird is surely a free & open source email platform, still it is lacking much functionality, which is found in MS Outlook. To be precise, Mozilla Thunderbird lacks personal data storage management. So, all-in-all, Thunderbird can’t be taken as a complete desktop-email-management-program. On the other hand, Outlook has it all to make it a complete end-to-end email management program. This is the reason why a good number of users look for the switchover and thus intend to export MSF to PST.
Can MSF Files Be Opened in Outlook?
The answer is NO! Converting the mailbox of MSF to PST is needed instead. There are two ways for it:
- Manual Way
- Using Some Professional Tool
Note: MSF files are the index files. They only store summary of emails and do not contain any email message. But since its linked with Thunderbird, people confuse it with mailbox files. SO, do note that to access Thunderbird email messages in Outlook, you must convert the MBOX file and not the MSF files.
