Manual Migration of Encrypted or Password-protected PST Files to Thunderbird
Thunderbird does not allow for importing of PST files directly, nor encrypted or password-protected ones. Outlook does not allow you to access the PST unless you know the password.
Problems you will run into:
- A password-protected PST file will not let you open or export the file—in order to do so, you must unlock the file.
- If the PST is encrypted, then Thunderbird cannot read the PST file in any way, nor can it be imported.
So, directly or manually migrating encrypted/password-protected PST files is impossible.
