Outlook notifications not working? Fix them on iPhone, Android and your computer

Outlook on your phone only notifies for Focused Inbox mail by default. How to fix notifications and sounds on iPhone, Android, Windows and Outlook on the web.

Outlook's phone app only notifies you about new mail in the Focused Inbox unless you tell it otherwise, so anything it sorts into Other arrives without a sound. That one default explains most of the "some emails notify, some don't" complaints. Open Outlook, go to Settings, then Notifications, and set Mail to All for each account.

If nothing notifies at all, the block usually sits further down, in Outlook's own Do Not Disturb or in the phone's permission for the app. The fixes below are split by device. I work on OLL.E, an app that can turn an Outlook notification into a phone call, and on iPhone it can only do that with our PinG keyring, because iOS keeps one app's notifications hidden from every other app. On Android it reads them directly.

A new email has to get past four filters before your phone makes a noise. First the account's notification level inside Outlook (All, Focused Inbox, Favorite People or None). Then Outlook's in-app Do Not Disturb. Then the phone's own switch for the Outlook app. And on iPhone, finally, whatever Focus is running. Any one of them can drop the alert, and none of them tells you it did. So you check them in that order, and you stop at the first one that is wrong.

Why am I not getting Outlook notifications on my iPhone?

Start inside Outlook, not in iPhone Settings. Most of the time the phone is doing what Outlook asked it to do.

In Outlook, open the menu at the top left, tap Settings at the bottom, then Notifications & Sounds. Under Mail, look at the level for each account. Focused is the default. Pick All if you want every email to notify.

Back in the menu, look for the bell icon. That is Outlook's Do Not Disturb, and if it is on, you have found the problem.

Next, the iPhone itself. Open Settings, then Notifications, scroll to Outlook and make sure Allow Notifications is on. If that is fine and Outlook is still quiet, open Settings, then Focus, pick the Focus you use and check whether Outlook is allowed under Apps. Scheduled Summary can hold alerts back too; it is under Settings, then Notifications, then Scheduled Summary.

Work accounts have one extra trap. Work accounts on Microsoft 365 enterprise plans can carry a Quiet Time schedule (Certain Hours or All Day) that mutes Teams and Outlook mobile notifications together, though calendar reminders still come through. If you set quiet hours in Teams once and forgot, Outlook goes quiet too. You find it under Notifications & Sounds, then that account's Do Not Disturb option, then During Quiet Time.

The notification sound on iPhone lives in the same screen. Under Mail, tap Sound and pick one, or pick Off. Calendar has its own Sound setting next to it, which is where Outlook calendar alerts get their tone.

Outlook notifications not working on Android

Android uses the same menus inside Outlook, with one label changed. The screen is called Notifications, not Notifications & Sounds. Set Mail to All for each account, check the bell for Do Not Disturb, and pick a sound under Mail, then Sound.

Then the phone. Microsoft's own help says you may also need to change Outlook's setting in Android's notification settings, and that is where people get stuck, because Android lets an app be allowed overall while one of its categories is switched off. Open Settings, search for Notifications, find Outlook in the app list and open it. Every category for mail should be on.

Outlook notifications not popping up on your computer

On a PC there are two Outlooks now, plus the web version, and each keeps its own switch. Windows sits on top of all of them.

Classic Outlook: go to File, then Options, then Mail. Under Message arrival, tick Display a Desktop Alert. The same section has a Play a sound box. To change the sound itself, quit Outlook, open Control Panel and search for Sound. On the Sounds tab, under Program Events, select New Mail Notification and click Browse. It only takes .wav files, so an .mp3 will not work.

New Outlook: go to View, then View Settings, then General, then Notifications, and turn on Mail and Calendar. Pick a custom sound under Mail, then Play Sound.

Outlook on the web: Settings, then General, then Notifications. Expand Mail or Calendar to choose how alerts show and whether they play a sound.

If all of that is on and nothing pops up, check Windows. Open Settings, then System, then Notifications, make sure notifications are on and that Outlook is allowed in the list of apps. Two details from Microsoft explain the odd cases. Desktop alerts don't show while an account is first syncing or during a manual Send/Receive. And a rule that moves mail out of the Inbox can stop the alert for that mail, which catches people who filter clients into folders.

Focused Inbox is why some emails never notify

Focused Inbox hides the emails people most need to see, and most users never notice why. Microsoft says it looks at the people you interact with and filters out noisy sources such as automatically generated or bulk email. That sounds sensible until you list what a working person actually waits for. An invoice from a billing system is automatically generated, and so is a contract sent through a signing service. That is the kind of mail the filter tends to push into Other. A first email from a new client has the same problem from the other side: it comes from someone you have never written to.

On the phone, Other means no notification by default. On iOS the badge count follows Focused as well. So the email isn't lost, it's just quiet, and you only find it when you happen to tap the Other tab.

The quickest fix is setting Mail notifications to All, which leaves the sorting alone and only changes what notifies. If you like the sorting, train it: open a message that landed in Other, tap the three dots, tap Move to Focused Inbox, then Always Move, and future mail from that sender goes to Focused. Or turn the sorting off. On the phone that is Settings, then Mail, then the Focused Inbox toggle. In new Outlook it is View, then View Settings, then Mail, then Message List, where you untick Sort messages into Focused and Other. Classic Outlook has Show Focused Inbox on the View tab.

A phone call for the Outlook emails that matter

Even with Mail set to All, an Outlook notification is a banner that disappears under the next twenty. OLL.E doesn't connect to your Outlook account; its only email connection is Gmail. What it can do is read the notifications the Outlook app shows on your phone, directly on Android and through the PinG keyring on iPhone. You type a watch as a sentence, naming a client or the subject you care about, like "invoice" or "contract", and when a notification matches, it calls you or sounds an alarm and sends a summary. Since it works from notifications, Outlook has to be notifying in the first place, so set Mail to All before you rely on it.

It won't reply to Outlook email for you. Auto-replies to email only work with Gmail.

If your Outlook problem is a setting, the steps above fix it without installing anything, and the Gmail version of this guide is at Gmail notifications not working. If the problem is that a banner is too easy to miss, OLL.E turns the Outlook emails you name into a call. On Android it needs nothing extra. On iPhone it needs PinG, the keyring, which is a separate purchase. There's a 7-day trial of Pro ($19.99 a month), and a free plan after that.
