Complete Guide"},"content":{"rendered":"<p><strong>In summary:<\/strong> The most efficient way to recover archived emails and view old mailbox data is to import mbox files to Thunderbird as Thunderbird internally stores emails locally in the mbox format. You can import MBOX files in Thunderbird using its inbuilt import feature or the ImportExportTools NG add-on, depending on the Thunderbird version. I have recently went through with different import techniques on different mailbox sizes and different Thunderbird versions and saw a few common problems. In this guide, I will be explaining all working methods with real problems that you may encounter and their practical solutions.<\/p>\n<div class=\"red-border\">\n<h2>Why Import MBOX Files into Thunderbird App?<\/h2>\n<p><a href=\"https:\/\/www.adviksoft.com\/mbox\/\">MBOX<\/a> file format stands best among the mostly used mailbox storage formats. It&#8217;s so because they are used by many email applications like Apple Mail, Eudora, Opera Mail, SeaMonkey and Thunderbird itself to store emails locally.<\/p>\n<p>There are many reasons to open and read MBOX files in Thunderbird.<\/p>\n<ul>\n<li>restore old email backups<\/li>\n<li>import emails from other email program to view archived emails<\/li>\n<li>handle orphaned MBOX files<\/li>\n<li>To open mailbox data without internet access<\/li>\n<\/ul>\n<p>Since Thunderbird stores mailbox data internally in MBOX structure, it can read imported mailbox files better than many other MBOX supported email clients.<\/p>\n<\/div>\n<h2>How Thunderbird Handles MBOX Files?<\/h2>\n<p>Before you begin the import process, it is helpful to understand how Thunderbird stores mailbox data internally.<\/p>\n<p><strong>Mailbox folders are stored by Thunderbird using:<\/strong><\/p>\n<ul>\n<li>MBOX mailbox files<\/li>\n<li>MSF index files<\/li>\n<\/ul>\n<p>The MBOX file is the actual email content, while the MSF file is the mailbox index to load faster.<\/p>\n<p><strong>While importing MBOX files:<\/strong><\/p>\n<p>Thunderbird rebuilds mailbox indexes, scans MIME email structure, maps folder hierarchy, indexes attachments and metadata.<\/p>\n<p><strong>Large MBOX files can temporarily increase:<\/strong><\/p>\n<p>CPU load memory consumption mailbox index time<\/p>\n<p>When i tested this method with 6GB MBOX archive that contains roughly 42,000 emails, then i saw that it caused issues in Thunderbird to index for several minutes before mailbox folders were completely available.<\/p>\n<h3>How to Import MBOX to Thunderbird 145, 144, 143?<\/h3>\n<p>First of all, make sure that you have installed the Thunderbird application on your system.
