How to open Outlook in every new tab

Updated October 21, 2026 · By the OnePane team

If you open Outlook dozens of times a day, it should be one click away, or already there. Browsers make this harder than it sounds, because none of them lets you pick a website for the new tab page. Here are the options that do work, from built-in settings to a new tab that shows your inbox and calendar at a glance.

Quick answer: to open Outlook when the browser starts, add https://outlook.office.com/mail/ (work or school) or https://outlook.live.com/mail/ (Outlook.com, Hotmail) as your startup page. To see your inbox and calendar on every new tab, use a new tab extension such as OnePane's.

Which Outlook address to use

Option 1: open Outlook when the browser starts

Chrome:

1. Click ⋮ → Settings → On startup.
2. Choose Open a specific page or set of pages → Add a new page.
3. Paste your Outlook address and click Add.

Edge:

1. Click … → Settings → Start, home, and new tabs.
2. Under When Edge starts, choose Open these pages → Add a new page.
3. Paste your Outlook address and click Add.

Safari (Mac): Safari → Settings → General, paste the address in Homepage, and set New windows open with to Homepage. Safari can also open it in every new tab: set New tabs open with to Homepage.

Firefox: ☰ → Settings → Home → Homepage and new windows → Custom URLs…, then paste the address.

Option 2: pin Outlook or install it as an app

• Pin the tab: right-click the Outlook tab → Pin. It shrinks to an icon at the left and comes back each time the browser restores your tabs.
• Install it as an app: in Chrome or Edge, open Outlook on the web and use the install icon in the address bar (or the browser menu's install option). Outlook gets its own window and a dock or taskbar icon.

Both keep Outlook close, but you still have to switch to it, and that's where the next twenty minutes go.

Option 3: your inbox and calendar on every new tab

Chrome, Edge and Firefox don't let you set the new tab page to a website, so this takes an extension. Pick one that asks for few permissions: a new tab extension that can read your tabs can see everything you browse.

OnePane turns the new tab into a start page with an Outlook Mail widget (unread count and the latest messages) and an Outlook Calendar widget (what's next today), next to weather, your Google or Apple calendars, news and to-dos. You see what's waiting without opening Outlook, and one click opens the message in Outlook when you need it.

1. Add the OnePane extension to Chrome (it also works in Edge and Brave). It asks for no permissions.
2. Open a new tab and create a free account.
3. Click ＋ Add widget → Outlook Mail and/or Outlook Calendar, then Connect Microsoft account. Access is read-only.

On Safari, skip the extension: set your homepage to https://onepane.page/app/ and choose Homepage for new tabs, as in option 1.

The Outlook widgets are part of Pro (US$2.99 a month). Every new account gets 7 days of Pro, no card needed. Work account asking for admin approval? Send your IT team our one-page note for IT admins.
