Whether you use Microsoft Outlook at work or for personal use, there is a spectacular range of Outlook add-ins available to help you conquer your everyday tasks.

We’ve rounded up the 20 best Outlook add-ins to help you boost your productivity and make your email workflow easier than ever.

Almost all add-ins are for your productivity, but we have listed a few for collaboration, communication, and a few for fun too! And yes, you can use most of them for free without paying a cent.

Remember: You will find most of the add-ins in the AppSource. But there are some which are available from third-party developers only.

Outlook add-ins for productivity

1. Outlook on the Desktop

Cost: Free

Key Benefit: Pin the Outlook Calendar to your desktop.

To get things done, you should schedule it. The Outlook on the Desktop add-in pins the calendar on the desktop, so you don't have to launch and click through Outlook's screens. You can customize the size and opacity to your liking.

To stay on top, the add-in allows you to switch from the calendar to other views like the inbox, contacts, tasks, and notes.


2. Grammarly

Cost: Free, with premium plans

Key Benefit: Write better emails without grammar and spelling errors.

If your Outlook is meant for professional emails, then Grammarly is a must-have add-in. Remember all your email etiquette and then use Grammarly to proofread your mail before you hit send. But it’s more than a spellchecker.

Grammarly is a smart tool. As you keep using Grammarly, it can also enhance your writing by spotting your common mistakes. Grammarly Premium offers advanced checks but the free version is good enough for everyday use.

3. Advanced Folders Watch

Cost: Free

Key Benefit: Set up alerts for specific messages in your Outlook folders.

Think of Advanced Folder Watch as an automatic filter that follows your rules to list down all critical emails. The rules are created with a wizard and you have complete control over them.

The add-in sits in your inbox and watches the predefined folders for the right conversations. The notification system can then remind you with a pop-up or curate the filtered emails in a special folder.

Advanced Folders Watch works with Outlook 2016, 2019, and Microsoft 365.



4. Text Lightning

Cost: Free

Key Benefit: Save time by reusing common text snippets in your emails.

Text Lighting is a powerful version of “Canned Responses” in Gmail. You can save the text snippets you commonly write and then reuse them in other emails.

The Outlook add-in can also set up conditional responses based on different variables you use to reply to messages. You can use different templates for the kind of responses you want to send.

Text Lightning works with Outlook 2016, 2019, and Microsoft 365.


5. Evernote

Cost: Free, with paid plans

Key Benefit: Organize notes and attachments in this ultra popular note-taking tool.

A crowded inbox can drown out valuable information. You need an information manager like Evernote to store the important bits when working on a project. The Evernote add-in lets you clip email messages and attachments from Outlook directly into Evernote.

Your Evernote notebook can also be the hub if you want to attach notes from Evernote to an email. Let’s also remember that Evernote allows you to share your notebooks with others.

Evernote works on Outlook Web and Outlook desktop versions.

6. Boomerang

Cost: Free, with paid plans

Key Benefit: Easily schedule your emails at later times.

Outlook allows you to delay or schedule email messages. But there are a few other features in Boomerang that make it a useful email assistant. For instance, you can track which links have been clicked in your email, and follow up if no one has opened them yet.

Boomerang has four tiers of subscriptions. You can try the free version out before you decide to upgrade.

7. Mr. Post - Email Inspector

Cost: Free

Key Benefit: Stay safe from scammers and phishers.

Scammers know how to scrape your email id and bombard you with phishing emails. Outlook has its own anti-phishing feature, but it helps to have a second sentinel. Mr. Post is the shield that tells you whether the email being read is safe.

Artificial intelligence and advanced email analysis techniques help protect your inbox against reckless clicks. The add-in also helps to visualize the meta-information in the email headers.

Mr. Post works with Outlook Web and Outlook desktop versions.


8. PayPal

Cost: Free

Key Benefit: Send and receive money without leaving your inbox.

PayPal needs no introduction. You can use the PayPal web app or the mobile app to send money to someone or use the convenience of this add-in within your email.

The add-in lives inside your inbox. Open the PayPal app, choose a friend, and send the money using the email address that Outlook autofill’s for you. All relevant information about your transaction flows back into your inbox.

PayPal works with Outlook Web and Outlook desktop versions.


9. Custom Signatures

Cost: Free

Key Benefit: Set up independent signatures for different recipients and accounts.

Outlook allows you to create one or more signatures for your multiple accounts. But if you are someone who likes to attach a different signature for different people, then Custom Signatures is for you. This add-in also works with Outlook Online.

Custom Signatures supports both plain text emails and HTML emails. No signature data is stored outside. The add-in displays a sponsored ad in the task pane.

Custom Signatures works with Outlook Web and Outlook desktop versions.


Outlook add-ins for collaboration

10. Dropbox for Outlook

Cost: Free, with paid plans

Key Benefit: Share large files from the cloud instead of attaching them.

You might wonder about the need to use Dropbox when Outlook has a more seamless relationship with OneDrive. But your or your collaborator's preference for Dropbox should negate that debate. Use this Outlook add-in to share files of any size.

Thanks to the cloud, you can also access any file in Dropbox from anywhere and attach it to your emails.

This add-in works with Outlook Web, Outlook 2019, Outlook 2016, and 2013. So far, this add-in does not seem to support Outlook 365.

13. DocSend

Cost: Free, and paid plans

Email attachments have their limitations. You must consider security too while sending proprietary business documents. DocSend solves the problems of attachment size and security with its solution.

You can share files up to 250MB with a simple, secure web link. Complete control even after hitting send, instant “read” notifications, and page-by-page analytics tells you who has opened the attachment and which parts have caught their eye.

DocSend works with Outlook Web and the Outlook desktop versions.


Outlook add-ins for communication

14. Translator for Outlook

Cost: Free

Majority of your email conversations might be in English. But some emails just might pop up in a foreign language. The official Translator for Outlook add-in from Microsoft can translate all these messages on the fly.

Responding to business emails with animated GIFs might not be a great idea. But who said you can’t have some fun with the personal ones?
