How to Use Outlook on Linux: Web, PWA, and an Unofficial Snap Wrapper

You can use Outlook on Linux through Outlook on the web, install it as a progressive web app (PWA), or use an unofficial desktop wrapper. Microsoft’s current sign-in page gives you email, calendar, contacts, and tasks in a browser, while a wrapper only places that web experience in its own window.

Choose the Outlook setup that fits your work

The browser route is the starting point because it uses Microsoft’s own service directly. A PWA and an Electron wrapper can improve window management, but neither turns Outlook into a native Microsoft Linux application.

Use Outlook on the web

Open Outlook on the web and sign in with your Microsoft, work, or school account. This route gives you the current Outlook interface without relying on a community package.

Keep Outlook in a normal browser tab for several Microsoft 365 services, or install it as a PWA after you sign in when it needs its own launcher and window.

Install Outlook as a progressive web app

A PWA is still the Outlook website, but your browser gives it a separate application window and desktop entry. Open outlook.office.com in Chrome, Chromium, Edge, or another browser that offers site installation, then choose the browser’s Install app action.

Because the menu label varies by browser version, confirm that the installed window opens Outlook’s Microsoft sign-in page before treating it as ready for daily use.

If you use other Microsoft services on the same machine, the OneNote on Linux guide covers another browser-first setup. A separate site window is useful when you want Outlook to stay out of a busy browser session.

Install the current unofficial Outlook Snap

Snapcraft lists outlook-ew as an unofficial Electron wrapper for Outlook on the web, with a publisher and permissions that you should review before you place work mail in the app.

sudo snap install outlook-ew

Run that command only on a distribution with Snap support enabled. The Linux package management overview explains how Snap differs from distribution packages and Flatpak, while the Snap versus deb example shows why package format changes desktop maintenance.

Avoid the older Prospect Mail commands that circulate in older tutorials because its former Snap listing is edge-only, has not been updated since 2023, and warns that the channel may be unmaintained. If you would rather use a graphical catalog, install applications through GNOME Software on Ubuntu.

Use Thunderbird when you need a mail client, not an Outlook window

Thunderbird is a separate mail client rather than a repackaged Outlook interface, so account support and calendar behavior depend on your organization’s Microsoft 365 or Exchange configuration.

A mail client changes the account workflow. Verify your organization’s connection requirements before you migrate from Outlook on the web, and use the Linux wget command guide if you later choose a standalone package download.

Verify the setup before you depend on it

1. Sign in and open your inbox, calendar, and contacts.
2. Send a message to an account you can check independently.
3. Create a test calendar event and confirm that it appears where you expect.
4. Review notification and clipboard permissions before you store work credentials in an unofficial wrapper.

For a simple Outlook workspace, use Outlook on the web or a PWA. Choose a third-party wrapper only when its separate window and desktop integration justify the extra maintenance and trust boundary.
