Easy and Quick Solutions"},"content":{"rendered":"<p><strong>Summary<\/strong>: Outlook users got stuck while importing OST files to Thunderbird. Therefore, through this post, we will figure out 2 easy and quick solutions to import OST to Thunderbird.<\/p>\n<p>Undoubtedly, Outlook is an excellent email client for individuals and organizations. But still, users prefer to use a free email client like Thunderbird. However, the problem arises when users fail to move the OST file data in Thunderbird. Recently, our support team received a lot of queries from clients asking for a smart way to import OST mailbox data to Thunderbird.<\/p>\n<h2>Why do users need to import an OST file to Thunderbird?<\/h2>\n<p>The main reason is the cost-effectiveness of the Thunderbird email client. Here are some common factors that lead users to import OST file items to Thunderbird:<\/p>\n<ul>\n<li>Thunderbird provides an easy and friendly layout that any novice can understand.<\/li>\n<li>Allow managing multiple accounts at once on a single platform.<\/li>\n<li>Thunderbird is easily accessible on various platforms like Windows, Mac, Linux, etc.<\/li>\n<li>Thunderbird allows storing large mailbox data without hanging issues.<\/li>\n<\/ul>\n<p>Also read: <a href=\"https:\/\/www.softaken.com\/guide\/preserve-folder-hierarchy-while-converting-ost-file\/\">Preserve Folder Hierarchy While Converting OST File<\/a><\/p>\n<h3>Can we import OST to Thunderbird?<\/h3>\n<p>Importing OST file items to Thunderbird is almost impossible with external tools, as there is no direct way to import the mailbox data from Outlook to Thunderbird. But we here offer you a two-step procedure, i.e., converting the OST file to PST format and then importing it to Thunderbird. Apart from this, you can use the professional solution that directly imports OST mailbox data to Thunderbird.<\/p>\n<h2>Manually Import OST file to Thunderbird<\/h2>\n<p>As we mentioned earlier, there is no direct technique to manually import OST email data to Thunderbird. To do so, you have to go through two steps:<\/p>\n<ul>\n<li>Export OST file items to PST file<\/li>\n<li>Import the exported file into Mozilla Thunderbird<\/li>\n<\/ul>\n<h3>Step 1. Export OST file to Outlook PST file format<\/h3>\n<ul>\n<li>Open the Outlook program on your computer.<\/li>\n<li>Hit the <strong>File<\/strong> menu \u2013 <strong>Open &amp; Export<\/strong> \u2013 <strong>Import\/Export<\/strong>.<\/li>\n<li>Pick the <strong>Export to a file<\/strong> option and press the <strong>Next<\/strong> button.<\/li>\n<li>Here, choose the <strong>Outlook file (.pst)<\/strong> option and hit the <strong>Next<\/strong> button.<\/li>\n<li>Pick the folder you want to export from your mailbox and hit the <strong>Next<\/strong> button.<\/li>\n<li>Finally, hit the <strong>Browse<\/strong> button to pick a destination and hit the \u2018<strong>Finish<\/strong>\u2019 button.<\/li>\n<\/ul>\n<h3>Step 2. Import the exported PST file to Thunderbird<\/h3>\n<ul>\n<li>Before this, make Outlook your default program for sending &amp; receiving emails. For this, go to Default programs \u2013 Set Default programs and pick Outlook.<\/li>\n<li>Now, launch <strong>Thunderbird<\/strong> and go to the menu option.<\/li>\n<li>Then, hit Tools and pick <strong>Import<\/strong>.<\/li>\n<li>Hit Import from Outlook and press <strong>Continue<\/strong><\/li>\n<li>Hit the \u2018<strong>Mail<\/strong>\u2019 option and then press the \u2018<strong>Next<\/strong>\u2019 button.<\/li>\n<li>Finally, complete the process by tapping the \u2018<strong>Finish<\/strong>\u2019 button.<\/li>\n<\/ul>\n<h3>Shortcomings of the manual technique<\/h3>\n<p>Though the manual technique is completely free. However, it has many demerits that you must consider. Let us find them here:<\/p>\n<ul>\n<li>To implement the manual technique, users require technical expertise<\/li>\n<li>There is a high chance of data loss if there is a network issue, malware issue, etc.<\/li>\n<li>You need to follow multiple steps, which makes this task complex and time-consuming.<\/li>\n<\/ul>\n<h2>An Expert Tool to Directly Import OST to Thunderbird<\/h2>\n<p>If you need a safe and reliable solution to import OST mailbox to Thunderbird, then go for <strong>Softaken <a href=\"https:\/\/www.softaken.com\/ost-to-mbox-converter\">OST to MBOX Converter<\/a><\/strong>.
