How to Convert Claws Mail to Outlook?

Jul 18, 2023 | By Deepak Singh Bisht

Claws Mail is a user-friendly, free email program popular among both personal and professional users due to its open-source nature and compatibility with Windows, Linux, and MAC OS. It has an impressive suite of features, including a calendar, RSS aggregator, robust security measures, and anti-spam capabilities.

However, there may come a time when you feel the need to switch to a different email program for various reasons - performance issues, slow application speed, or simply because your requirements have changed. One such commonly preferred alternative is MS Outlook, known for its advanced features and seamless communication capabilities. If you're considering migrating from Claws Mail to Outlook, you're at the right place!

Please note that there isn't a direct way to transition from Claws Mail to Outlook. But with the help of a few steps and possibly an additional tool, the process can be made easier. Let's take a look at these steps:

Manually Migrating from Claws Mail to Outlook:

Choosing to manually migrate from Claws Mail to Outlook can seem challenging, but it is not only effective, it's also a budget-friendly choice since it requires no additional expenditure on tools or software. This method requires you to have both Mozilla Thunderbird and MS Outlook installed on your computer, as we'll be using these platforms as intermediaries in the process. Additionally, a specific add-on for Thunderbird is needed, which is freely available. However, do note that this method demands careful attention to each step and a fair degree of patience to ensure data integrity during the process. Now, let's delve into the steps:

  2. Go to the File menu and select Export to MBOX file option
