Outlook vs Thunderbird Comparison

Those are some of the basic features of the two email clients you will see if you were to download and use that software. But what about everyday usage?

Both platforms are distinct in their creation and are slightly different when it comes to fulfilling the same purpose. Let’s put it in perspective if you were to begin using these email clients every day.

User Experience

You will start to tell if you love your email system or hate it the more you use it. Before you waste time downloading and setting up your account, let’s look at the user experience of Mozilla Thunderbird vs Outlook so you know what to expect.

Thunderbird

Thunderbird logoIf you were looking at the open Thunderbird application, you might notice that its appearance is behind on updates. While the system is functional and easy to use, it is rather slow at updating from time to time.

Advantages

If you need to search on the app, you can use tab navigation to have multiple tabs open without losing sight of your inbox. This is very beneficial if you need to look for multiple messages and cross-check yourself in the process.

Mozilla Thunderbird also allows for cross-platform access. You can download this email client on all computer systems, though its primary system is Linux.

Disadvantages

Other being late to the party with its design and updates, Thunderbird’s biggest user-experience drawback is its lack of mobile access.

To view your emails or send a message, you have to have a desktop. This can be a turn-off for businesses who need their email on the go.

Outlook

Outlook

While Outlook looks nice and offers a lot of excellent features, it’s not as easy to use as Thunderbird. However, it does offer more customizable features and the app has had several upgrades over the years as opposed to its competitor. If you’re able to spend some time adjusting to the platform, you might come to find its features fit your needs better.

Advantages

Outlook has more advantages than it does disadvantages. For starters, you can use this email client on your phone on the go as well as on your desktop. To have the running app, you will need to download it on your phone and sign in with your Microsoft account.

Microsoft Outlook also has a sleek design and is very appealing to the eye while still giving its users the freedom to customize the app. Along with its high-quality features, users can really benefit from this email client.

Disadvantages

The biggest disadvantage Outlook has compared to Thunderbird is no tab navigation. If you were to start searching in your email, you will lose your place on the original screen. This might pose some annoyance for someone trying to heavily search a previous message.

Design Simple/Customizable Complex/Customizable
Cross-Platform Compatibility Just desktop

Windows, macOS, Linux

Desktop and mobile

Windows, macOS, Android, iOS

Multiple-Tab Navigation Yes No
User-Friendly Yes Yes

Email Account Management

If you are trying to balance having more than one email, then the email client of your choosing must have the functionality to manage those separate accounts.

Having the ability to host your accounts in one place makes it easy to serve as a one-stop shop for switching back and forth between those email addresses instead of having to open up endless web tabs.

Here’s how email account management is set up in Thunderbird vs Outlook 2017.

Thunderbird

Mozilla Thunderbird has several beneficial features for hosting and viewing your several email accounts. The good news is that you have unlimited accounts through this email client and there’s a unified inbox feature that will display all messages from all accounts.

Some functionality purposes for email management can be added on through installing plugins if your needs are not met as is.

Advantages

Apart from its capability to view a unified inbox, the add-ons you can install for your email account can enhance Thunderbird’s existing features by allowing you to merge emails, select conversation viewing, and postpone sending mail.

Disadvantages

While Thunderbird can show a unified inbox, it’s very selective in the accounts that will be a part of the unified viewing. Plus, the need for add-ons to achieve your goals can feel annoying to have to go out of your way to install them and become acquainted with how to use them.

Outlook

When it comes to email account management, Outlook does not offer some features that Thunderbird does, but then again, Outlook offers features that Thunderbird doesn’t.

Advantages

Outlook shares the postponed email send as Thunderbird does, but with Outlook, you don’t need an add-on to access this feature. One of the advantages Outlook has in this area as opposed to Thunderbird is read receipts, which will let you know if your email has been opened and read.

Disadvantages

Unlike Thunderbird, there is no unified viewing in Outlook. While Outlook does offer the feature to have other accounts, you can only have up to 20 different addresses whereas Thunderbird offers unlimited accounts.

Feature Thunderbird Outlook
Unified Inbox Yes No
Email Filtering Yes Yes
Postpone Send Add-on only Yes
Read Receipts No Yes
Conversation View Add-on only Yes
Email Account Creation Unlimited Limited

On top of its easy configuration, there are over 1,200 add-ons you can add to your Thunderbird email to enhance its features to your customization needs.

Disadvantages

The only downfall this app set up has is its lack to allow the generation of email scripts.

Outlook

Whereas Thunderbird is simple and easy, Outlook is more detailed when it comes to its app setup. Once you’ve downloaded the system, you will need to login and verify your Microsoft 365 account before you’re able to do anything else.

Advantages

Disadvantages
