Microsoft Outlook is one of the oldest and most widely used email applications. You may use it if your job demands you to send and receive emails frequently. But nowadays, users face the “Outlook mentions not working” issue. If you’re also trying to resolve this problem, read this post. I have thoroughly examined this issue and found proven ways that I am mentioning in this post. Let’s dive into it!

Part 1. Get to Know About @mentions Outlook

What are @mentions in Outlook?

Without much fanfare, Microsoft frequently upgrades its software and adds new capabilities. This year’s new feature, "Mention," includes the ability to tag someone in a message and quickly alert them. 

This feature can speed up the convenience of interacting with Microsoft applications. It is similar to tagging someone in a chat message.

How does @mention work in Outlook?

Usually, when we send email content, we need to enter recipient names in the “ to” or CC and BC along with the subject. But with the @mention symbol, you need to choose from the contact name and send an email to that address.
