Common Reasons to Move from Mozilla Thunderbird to MS Outlook

Outlook is an information management software offered by Microsoft. You can use it in two ways – either as a separate application or with the entire pack of MS Office. It provides you with numerous useful features, such as an email scheduler, task manager, contact manager, and more.

Thunderbird, a project from Mozilla Firefox, aims to provide you with a cross-platform email management tool. It eases the work of managing multiple email accounts. It brings valuable features, like a virtual folder, finding messages, and quick search.

Mozilla Thunderbird to MS Outlook

Why Switch from Thunderbird to Outlook?

Even though Thunderbird offers many useful features, many people still prefer Outlook. There are many typical reasons for migrating from Thunderbird to Outlook. We’ve compiled some of them below.

  1. Filtering out Spam

The lack of a spam filter option in Mozilla Thunderbird irritates users who rely on it to keep their mailbox free of unwanted emails. On the other hand, Microsoft Outlook comes pre-installed with a robust spam filter that protects you from phishing assaults.

  1. List of Upcoming Tasks and Appointments

Mozilla Thunderbird cannot organize your daily chores and plan meetings with co-workers or customers. But these features are available in Outlook, making it simple for users to keep track of the tasks.

  1. Slower Development of the Product

There aren’t a lot of developers who support Thunderbird, which slows down development and reduces the number of updates. Furthermore, most customers want an app that is always up-to-date and has rapid access to new versions.

  1. Streamlining the Process of Workflow

Automating the process of managing email messages is not possible with Thunderbird. MS Outlook allows you to set up automated process rules.

  1. Scalability and Security

For every business, it’s essential to have an email system that is integrated with high security and capable of scaling as the business grows. No significant security protections are built into Mozilla Thunderbird. As a result, MS Outlook is a great option.

  1. Email Client Configuration Add-on is required

The POP3, IMAP, and SMTP email protocols are all supported by Thunderbird, but none of them can be configured without an add-on. But all these email accounts can be configured in MS Outlook without the need for any add-ons.

  1. Using Several Email Accounts at Once

Thunderbird can handle multiple email accounts, although there is a limit. However, multiple email accounts, including IMAP and POP, can be used simultaneously in MS Outlook.

  1. Communication Tool Integration

Thunderbird does not have any communication tools connected with it. But communication tool, such as MS Teams, is already integrated with Outlook.

  1. Interface That’s Easy-to-Use

Thanks to regular upgrades and new features, Mozilla Thunderbird indeed has a robust user interface, but Outlook’s user interface is much superior.

  1. Frequent Updates

MS Outlook receives regular enhancements to maintain its robustness and trust. On the other hand, Thunderbird does not get any upgrades because of a lack of developers.

Some Outlook Features That Will Make Your Life Easier

Reminds you of Attaching the File

Whenever you write down an email and include words, like attached or attachments but forget to attach them, Outlook won’t let that happen. It will remind you to attach the file you discussed in the email. Within the receiving reminder, you can stop the sending process and take a look at what you have forgotten.


You probably have sent out an email to several co-workers, but you only need one or two of them to answer? In this case, most people are likely to use text effects, such as bold or underline, to highlight their names. But, now you’ve another better option.

  • Type @ followed by your co-worker’s name. You will see many things happening.
  • The name will be added to the line of your email message.
  • You will notice the name highlighted in the body of the message.
  • When your co-workers receive the message, the @ symbol will show them their name is mentioned.

Ignore the Unwanted Conversation

If you are a large company worker, then this has probably happened to you at least once. There’s an email thread disturbing you from your actual work. Someone may have just added you to a distribution list without your permission.

Now, there’s no need to remove every message that arrives in the thread. You can ignore the whole conversation. All the messages from that conversation will be passed to the Deleted Items folder without even disturbing you.
