Convert or transfer emails from Thunderbird to Outlook 2019, 2016, 2013, 2010

Nowadays people are using MS Outlook for organization and personal uses. It is the best desktop-based email client rather than others like Mozilla Thunderbird, Eudora, Opera Mail, Postbox, and Sea Monkey, etc. If they need to migrate from all the above-mentioned email clients like Mozilla Thunderbird to Outlook, for those users here I am going to describe the need and working process of the software.

In today’s arena, email clients play a vital role in sending and receiving mails. MS Outlook is widely used as a flexible mail client with robust features such as contact management and social media connectivity. It has a simple and user-friendly interface for easy handling and also helps the user to set appointments and reminders in Outlook calendars. It s a highly secured mailing client that protects their data from spams and other phishing activities. MS Outlook has various versions such as 2019, 2016, 2013, 2010, 2007, etc. The Outlook creates two types of data files i.e OST (offline storage table) and other is PST (personal storage table). On the other side, Mozilla Thunderbird is a mail client that is used thousands across the world. It uses the MBOX data file.  It is free, open-source, less cost and workable with multiple platforms like Ubuntu, Linux, and Windows. Having too many features but Thunderbird has some constraints that incline users towards Outlook.
