Outlook PWA stands for Progressive Web App. It is a way to install the web version of Outlook as an app on your computers home screen or taskbar. When you install the web version of Outlook as a PWA, you can do things like pin and launch the web version of Outlook from your computers home screen or taskbar and access your account while youre offline.

PWAs are essentially still websites, but they include better caching, notification features, and background functionality to make them appear and function more like traditional apps. Microsoft has been slowly adopting PWAs for Windows apps since last year, and Outlook is a sign that we may see similar apps for the company’s other Office products like Word and Excel.

To install Outlook as a PWA, you can follow these steps:

1. In Microsoft Edge, sign in to your Outlook on the web or Outlook.com account.
2. Select Settings and more at the top of the window.
3. Select Apps > Install this site as an app.
4. In Google Chrome, sign in to your Outlook on the web or Outlook.com account.
5. Select Customize and control Google Chrome at the top of the window.
6. Select Install Outlook.

Once you have installed Outlook as a PWA, you can launch it from your computers home screen or taskbar and access your account while youre offline.
