Best Solution to Export Thunderbird to PST
A few days back, a user asked how to move from Thunderbird to Outlook after years of using Mozilla’s client. Many face the same situation because Outlook offers better connectivity with Exchange, POP/IMAP, calendars, and organizational controls. If you’re planning to export Thunderbird to PST, you may have already noticed that both email platforms use different file formats—Thunderbird uses MBOX, whereas Outlook relies on PST. This rules out any direct import method and makes traditional manual migration a hassle.
After trying manual methods like drag & drop (EML conversion) or IMAP syncing, I found they’re time-consuming, lengthy, and risky for large volumes. A much easier solution is to use the SysInfo Thunderbird Backup Tool, which simplifies the entire process. It can automatically detect Thunderbird mailboxes, preview emails, preserve folder structure, and convert data directly into PST without any other apps. One feature I liked is the external storage backup option that allows saving Thunderbird data to local drives for long-term access. Anyone switching to Outlook will find this tool much faster and more reliable than manual migration.
