In one sentence, describe what the following article is about:

Go to https://www.outlook.com/ in your browser. This will open your inbox if you're logged into Outlook. If you aren't logged in, enter your email address and password when prompted. It's a tab on the left side of the page. Doing so opens your Outlook deleted emails page. If you don't see this option, click in the upper-left side of the page to prompt it to appear. Scroll through the contents of the Deleted Items folder until you find the email that you want to recover. If you can't find the deleted email but you know you deleted it within 14 days ago, you can still recover the email. If you're using the beta version of Outlook, you'll need to disable the beta before doing so. Hover over the email, then click the circle in the top-left corner of the email to select it. If you're not using the beta version of Outlook, you'll instead click the checkbox in the upper-left side of the email. It's at the top of the Outlook page, just below the "Search" bar. Doing so will place back in your inbox the selected email(s). Any restored emails will be placed back in your inbox in chronological order.
Open your Outlook inbox. Click Deleted Items. Find the email that you want to recover. Select the email(s). Click Restore.
