Microsoft Outlook is one of the most popular email clients available. The free accounts provide 15GB of email storage and 5GB of cloud storage, integrating well with programs like Word, Excel, PowerPoint, and more. Outlook apps provide additional features that can make handling email even easier. 

Email accounts can quickly be overrun by subscriptions and updates and become a struggle to keep up with. In fact, only 32% of all messages even get opened. Outlook apps can help you take control of your inbox, be more efficient with your work, and save time performing repetitive tasks. 

Let's review the best Microsoft Outlook apps.

What are Outlook apps?

Outlook apps are software designed to extend Outlook's functionality. These add-ons can make your inbox more efficient and provide a better email experience. Outlook apps are made by third-parties, so they won't always be listed in the 365 app store. 

What are the best Outlook apps?

Here are our top Outlook apps that will help you boost productivity and take control of your inbox:

Superhuman

Superhuman is the fastest email experience ever made. Since email is the preferred method of communication for most people and businesses, it's essential to make the most of the time you spend in your inbox. Superhuman will save you four hours or more, every single week.

Whether it's writing emails, reading them, or creating reminders, Superhuman is designed to help you fly through your inbox. With Instant Reply, every email gets three pre-drafted replies, and all you have to do is simply edit and send. With Auto Summarize, you’ll see a 1-line summary above every conversation that updates instantly.

Superhuman is ideal for teams, whether large businesses or sales teams. Teams move faster, stay in sync, and get more done with Superhuman. Using Shared Conversations & Team Comments, your entire team can comment directly on an email, with no risk that internal comments leak. Meanwhile, Snippets allows you to insert commonly used phrases, paragraphs, or whole emails with a simple keyboard shortcut.

Our Autocorrect fixes errors as you and beats the autocorrect in Gmail and Outlook across multiple benchmarks. With Team Scheduling, there’s no need for time zone math or back-and-forth threads. You can instantly see when your team is free and schedule meetings right from Superhuman. 

Plus, Superhuman works wherever you do — on Android and iOS devices, as well as Windows and Mac computers.

Grammarly

The Microsoft Outlook email client includes basic autocorrect, which looks for simple grammatical issues, spelling mistakes, and punctuation. 

Grammarly can be used alongside Outlook to increase your proficiency and help you clean up what you've written. 

The free version can provide most of what you need, while the paid version unlocks even more powerful features, such as sentence restructuring, shortening, simplification, and tone changes. 

Grammarly's suggestions are served as easy-to-click replacements, so you can include only the parts you want to change.

MeisterTask

MeisterTask is a powerful way to manage projects and tasks and create to-dos that often come with business emails. With MeisterTask in Outlook, you can take an incoming email and generate an actionable task from its content without ever having to leave your inbox. 

The app is secure, allowing you to store work in a central place for everyone to see with email integration. That way, there's no need to open a new window to manage your next task.

Calendly

Managing your schedule can be challenging on your own. Calendly works as an assistant, allowing you to automate the scheduling process. You can send someone a link to your Calendly account, where they can then select a day and time that works for them — all while being linked to your Outlook calendar. 

Once your calendar is booked — or if days are blocked out — Calendly can prevent them from scheduling meetings when you're unavailable. Because it's linked directly to your Outlook calendar, you can see what meetings were scheduled and simply click the relevant links to automatically join when the time comes.

Trello

For teams with a lot to manage, Trello is a great way to keep everyone on the same page. Trello lets you and your team easily track what they're working on and see who's working on what at a glance. 

With Outlook, you can integrate Trello calendars into your email calendar. This way, you won't have to open the app to see due dates or important tasks. Instead, simply visit your Outlook calendar to stay up to date on your workload and your team's.

DocuSign

If your company needs signatures on important documents, DocuSign helps lift that burden. The old-fashioned method of printing, signing, scanning, and sending a document back is gone. With DocuSign, all your important signatures are collected electronically. 

DocuSign for Outlook lets you take care of basic tasks directly from your inbox. You can also sync DocuSign with your Office365 account and OneDrive as needed.

Boomerang

Boomerang upgrades the experience of using Outlook by providing many features that are otherwise missing. You gain more control over scheduling emails, making reminders for follow-up messages, and tracking how your replies are interacted with. 

The app provides analytics that let you see your click-through rates, open rates, replies, and read receipts. By reviewing your analytics, you can create more effective messages.

The bottom line

Outlook on its own is a powerful email client with lots to offer. However, depending on your needs, there are also apps that can integrate with Outlook to elevate your experience. 

Supercharge Outlook with Superhuman, the most productive email app ever made. Get started now and save four hours or more, every single week.
