Here Are 2 Tested Methods Explained<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There are two ways to handle OST to MBOX conversion. A direct manual option does not exist, and the process involves technical steps. We recommend using a dedicated converter tool for an error-free and easy conversion process. Below are the methods to consider:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Manually_Convert_Outlook_OST_File_to_MBOX\"><\/span>Manually Convert Outlook OST File to MBOX&nbsp;<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>This method involves converting the OST file to PST first and then importing the PST into the Thunderbird application. Follow the step-by-step procedure given below to start the process:<\/p>\n\n\n\n<p><strong>Step 1: Convert OST to PST in Outlook<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Open your <strong>Outlook<\/strong> application and go to <strong>File<\/strong>.<\/li>\n\n\n\n<li>Click on <strong>Options <\/strong>&gt; <strong>Advanced.<\/strong>&nbsp;<\/li>\n\n\n\n<li>Then, look for the Export section and select <strong>Export<\/strong>.<\/li>\n\n\n\n<li>Choose <strong>Export to a file<\/strong> and select <strong>Outlook Data File (.pst)<\/strong>.<\/li>\n\n\n\n<li>Pick the mailbox to export and choose the destination to save the PST File.<\/li>\n\n\n\n<li>Click <strong>Finish<\/strong> to begin the export process.<\/li>\n<\/ol>\n\n\n\n<p><strong>Step 2: Import PST into Thunderbird<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Open <strong>Thunderbird<\/strong> and navigate to <strong>Tools<\/strong> &gt; <strong>Add-ons<\/strong> &gt; <strong>Extensions<\/strong>.<\/li>\n\n\n\n<li>Use the Search bar and search for <strong>ImportExportTools NG<\/strong> and install it.<\/li>\n\n\n\n<li>Make sure that your PST File is accessible in MS Outlook.<\/li>\n\n\n\n<li>In Thunderbird, after the add-on is installed, go to <strong>Tools<\/strong> &gt; <strong>ImportExportTools NG<\/strong>.<\/li>\n\n\n\n<li>Select <strong>Import Outlook PST<\/strong>. Choose the desired PST File and follow the on-screen instructions.<\/li>\n\n\n\n<li>Once the emails are imported, they will be saved in Thunderbird.<\/li>\n\n\n\n<li>Right-click on the folder where you have imported emails and select <strong>Export<\/strong> to export the emails as MBOX.<\/li>\n<\/ol>\n\n\n\n<p><strong>Limitations:<\/strong> This method becomes inefficient when handling large OST Files. It is a time-consuming process. It contains technical steps and, therefore, is not suitable for non-technical users.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Professional_Approach_to_Convert_OST_to_MBOX_without_Outlook\"><\/span>Professional Approach to Convert OST to MBOX&nbsp;without Outlook<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Manual conversion gets the job done, but is usually lengthy and prone to errors.
