If you have calendars in the form of an MBOX file and are looking for ways to examine Thunderbird calendars, then this article will help you. Here, we present two different methods to view calendars in Thunderbird.

Mozilla Thunderbird is one of the email programs that are used on Mac, Windows, and Linux operating systems. It is a free open-source email client that uses MBOX files to import and export the data, a file format that stores the collection of emails with attachments. Thunderbird is not only used to manage emails but also to manage address books, which contain all your contact information. Also, calendars are used to schedule events, manage important dates, etc.

To view any mailbox items such as calendars, contacts, or events in Thunderbird, you have to use add-on extensions. Because the program doesn’t have an option to import or export the data. Thunderbird extensions, or add-ons, are the additional features you can use in the program after you install it. There are various addons for different purposes, and you can only add them from the official website, which is free to download. But there are other methods, too, that can easily allow you to read Thunderbird calendars.

Methods to View Calendars in Thunderbird

There are mainly two types of methods available: the first is manual, in which we open your MBOX file that contains calendars in Thunderbird using the add-on. The add-on is free, and you can easily use it. The next method is to use a third-party tool where, without the help of Thunderbird, you can easily view and examine Thunderbird calendar. So, these two are the methods that you can use.

• Install add-ons and use them to import and see the calendars.
• Use the third-party tool to view the data without the help of a program.

View Calendars in Thunderbird by Manually

When you have a normal MBOX file that contains emails with attachments, the Import/Export Tools NG add-on is used to view the file. Now, if you have an MBOX file containing calendars, this addon can also be used. For this, you have to first add the import/export add-on in Thunderbird. Then, follow the steps.

• Install Import/Export Tools NG from addons.thunderbird.net.
• After that, open the Thunderbird program and go to the Tools menu.
• Select the import/export tool and click on the Import MBOX file.
• Click on import directly for one or more mbox files and click OK.
• Browse the location of your file and click on the Import option.
• Go to the file where your calendars are and view them.

Limitations of the Manual Method

This method is free and simple, but there are times when you have trouble while using it.

• It is a time-consuming process, and you have to import the files one by one.
• There are problems while you are importing the files into the program.
• Any corrupt or damaged file cannot be imported into the program.
• Issues like missing data or not maintaining folder hierarchy.

Examine Thunderbird Calendars in Third-party Tool

The manual method is not an effective way to view calendars in Thunderbird, as it has many drawbacks rather than benefits. But this method doesn’t have any such problems, because it is free MBOX Reader Tool provided by FreeViewer. We use this tool because it allows users to view all the contents, like emails, contacts, calendars, and other mailbox items, in a very precise manner. Moreover, you can enjoy other features as well.
