Are you tired of seeing that pesky number of unread messages in your Outlook inbox? Fear not! There’s an easy way to mark all messages as read and clear that notification for a clutter-free inbox.

Step by Step Tutorial on How to Mark All Messages as Read in Outlook

Before diving into the steps, let’s understand what we’ll achieve by following this guide. By marking all messages as read, your inbox will appear cleaner, and you’ll be able to focus on the emails that truly require your attention.

Step 1: Open Outlook

Open your Outlook application or log in to your account if you’re using the web version.

This is the starting point. Ensure you’re logged in with the correct credentials and have access to your inbox.

Step 2: Navigate to the Inbox

Go to your inbox where the unread messages are located.

You might have multiple folders or subfolders, so make sure you’re in the right place where the unread emails are piling up.

Step 3: Select All Messages

Use the select all option to highlight all the messages in your inbox.

In most Outlook versions, there’s a checkbox at the top of the message list that allows you to select all messages with a single click.

Step 4: Mark as Read

Right-click and choose the ‘Mark as Read’ option, or find the ‘Mark as Read’ button in the Outlook toolbar.

Once you’ve selected all messages, the ‘Mark as Read’ option should be easy to find within the right-click context menu or the toolbar options.

After you’ve completed these steps, you’ll notice that the number of unread messages will drop to zero, and your inbox will look much tidier. It’s a small action that can make a big difference in your email management routine.

  • Use the search function to filter out important messages that you might want to keep unread.
  • Customize your Outlook settings to mark messages as read after previewing or opening them.
  • Consider creating rules to automatically mark certain messages as read upon arrival.
