We will look at two methods. First one, exports the calendar in .ics file. The second one, export it as a CSV file. Take a look.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Manually_Export_Calendar_from_Thunderbird_to_Outlook\"><\/span>Manually Export Calendar from Thunderbird to Outlook<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The Calendar events in Thunderbird are exported in the ICS file format. Then, we import this .ics file into Outlook. It works for complete or selective calendar transfer.<\/p>\n\n\n\n<p>The following are the steps to begin exporting:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>In <strong>Thunderbird<\/strong>, head to the <strong>Calendar<\/strong> tab.<\/li>\n\n\n\n<li>Then, select the calendar you wish to export.<\/li>\n\n\n\n<li>After that, right-click on that calendar and select<strong> Export Calendar<\/strong>.<\/li>\n\n\n\n<li>Next, pick the location to save the file and ensure the file type is <strong>.ics.<\/strong> Click <strong>Save<\/strong>.<\/li>\n\n\n\n<li>Now, open the <strong>Outlook<\/strong> application.<\/li>\n\n\n\n<li>Navigate to <strong>File<\/strong> &gt; <strong>Open &amp; Export<\/strong> &gt; <strong>Import\/Export<\/strong>.<\/li>\n\n\n\n<li>Afterward, select <strong>Import an iCalendar or vCalendar file<\/strong> &gt; <strong>Next<\/strong>.<\/li>\n\n\n\n<li>Lastly, browse and select the file and tap <strong>Ok.<\/strong><\/li>\n<\/ol>\n\n\n\n<p><strong>Limitations: <\/strong>The attachments of the calendar events are not imported into Outlook. Also, importing large ICS files may slow down the process by several hours.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Move_Thunderbird_Calendar_to_Outlook_Manually\"><\/span>Move Thunderbird Calendar to Outlook Manually<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>With this method, users can map the specific fields as per their needs. Because we export the Calendar via CSV format and then import it into Outlook.&nbsp;<\/p>\n\n\n\n<p>These are the steps to initiate the migration process:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>First, open the <strong>Thunderbird<\/strong> application and click on <strong>Tools<\/strong>.<\/li>\n\n\n\n<li>After that, press <strong>Add-ons and Themes<\/strong> &gt; Search and install <strong>ImportExportTools NG<\/strong>. Restart Thunderbird.<\/li>\n\n\n\n<li>Now, go to the <strong>Calendar<\/strong> tab and choose the calendar you want to export.<\/li>\n\n\n\n<li>Then, right-click the calendar and select <strong>Export<\/strong> &gt; <strong>Export as CSV<\/strong>.<\/li>\n\n\n\n<li>Choose the location on your computer and save the file as CSV.<\/li>\n\n\n\n<li>In <strong>Outlook<\/strong>, go to <strong>File<\/strong> &gt;<strong> Open &amp; Export<\/strong> &gt;<strong> Import\/Export<\/strong> &gt; <strong>Import from another program or file.<\/strong><\/li>\n\n\n\n<li>Now, choose <strong>CSV<\/strong>, locate and select the CSV file, and click <strong>Next<\/strong> &gt; <strong>Finish<\/strong>.<\/li>\n<\/ol>\n\n\n\n<p><strong>Limitations: <\/strong>This process does not import the calendar attachments. The user needs to have technical knowledge.&nbsp;<\/p>\n\n\n\n<p>Not only calendar events, but most users also prefer to export other items as well. Such as Thunderbird emails, contacts, and other mailbox data. Let\u2019s see how we can export Thunderbird emails to Outlook.<\/p>\n\n\n\n<p>The <strong>Cigati <a href=\"https:\/\/www.cigatisolutions.com\/thunderbird-backup-tool\/\">Thunderbird Backup Tool<\/a> <\/strong>is a smart and flexible solution to export Thunderbird emails to Outlook.
