Quick Methods to Import PST Files to Mozilla Thunderbird Email Client

Microsoft Outlook comes with the MS Office Suite subscription. Nowadays, users can also purchase the Microsoft 365 cloud subscription with various plans and pay the price accordingly. You can also purchase Outlook separately and use it. If your subscription plan has ended and you do not want to upgrade it, then you need to migrate the account to a new platform.

Mozilla Thunderbird is a free email client that you can install and use to manage your emails. Just like Outlook, you can add your business account in Thunderbird and communicate with your client. Thunderbird is the product from the Mozilla Community that designed it for the Linux Operating System originally. Later, it was introduced for the macOS and Windows platforms also. Since its introduction, Mozilla has consistently upgraded it and giving it a stable function environment.

Limitations of the manual process to import PST files

  • For the IMAP-based accounts, the IMAP should be enabled to allow Outlook to export the PST file.
  • When the user exports the PST file, then there are filter options available to apply on data. If the PST file has filtered data, then only such data will import.
  • Only a single account’s PST file can be imported in a single cycle.
  • A sudden abruption in the import process can corrupt both PST and the destination Thunderbird account.
Conclusion

Whenever you are using Outlook for professional use and want to adopt Thunderbird for the same account, then you should not remain dependent on any manual process.

The manual process has many limitations and it can also corrupt the data if the process is stopped midway. The file format of the Thunderbird is MBOX, so you should use professional conversion software to convert PST to MBOX format. After the conversion, you can add the MBOX file to Thunderbird and use it easily. The professional software will make sure that you can convert large-sized data files fully. You can easily manage the content, filter them, and rename them also. Finally, a process report will show the status of each converted item.
