This article explains how to make Outlook remember your email password. It includes troubleshooting tips for when Outlook won't remember your password. This information applies to Outlook 2019, Outlook 2016, Outlook 2013, Outlook 2010, and Outlook for Microsoft 365.
Microsoft Outlook requires you to type your password into a password box every time you open your email. This is great for security purposes, but if you're the only one using your computer, it's safe to save your password in Outlook.
When you let Outlook remember your password, you can receive and send email without having to enter your password every time you open Outlook. Plus, you can create a complex password that you don't have to remember or constantly retrieve from your password manager.
