Microsoft Outlook is often pre-installed on Xiaomi smartphones, especially if the device was sold with Microsoft-branded services. Even after manual removal, the program can “restore” after system updates or appear in the list of system applications that MIUI does not allow to uninstall using standard methods. In this article, we will discuss all working ways to remove Outlook, including hidden settings MIUI, ADB commands, and explain why the application can come back.
It is important to understand that complete deletion (as opposed to disconnection) requires superuser rights or special tools. If you use Outlook for work mail, export data first - after uninstallation, all emails, calendars and contacts will be irrevocably deleted from the device (but will remain on Microsoft servers). For Xiaomi 12/13/14 Pro models and flagships with HyperOS, the process may be different - we will specify the nuances.
Why is Outlook not removed in the standard way?
On Xiaomi smartphones, the Microsoft Outlook app can be:
- 📦 Pre-installed system software - sewn into the firmware MIUI/HyperOS and protected from removal.
- 🔄 Recovered after updates — MIUI Automatically returns remote applications when reset or upgrade.
- 🔒 Associated with a Microsoft account – if you logged in through Settings → Accounts, system considers Outlook "necessary».
- 📱 Office package – sometimes installed with Word/Excel via Microsoft Launcher.
To check Outlook status on your Xiaomi, go to Settings → Apps → App Management → Outlook. If the Remove button is inactive or not, the app is system-based, and alternative methods will be needed.
Method 1: Standard removal (if the button is active)
If Outlook was manually installed by you (not preinstalled), you can delete it through the app menu:
- Open Settings → Applications → Application Management.
- Find Microsoft Outlook in the list (use search if there are many apps).
- Click "Delete" and confirm the action.
If there is no Delete button but there is a Disable button, it means that the application is system-based, and shutting it down from the menu and stops background processes, but does not free up the memory completely.

Before deleting, check if Outlook is used to sync workmail over Exchange.Some corporate policies require an app to access email.
Method 2: Removal via ADB (without root)
The Android Debug Bridge (ADB) tool allows you to remove system applications without superuser rights, which works on all Xiaomi smartphones (including the Redmi Note 12/13, POCO X5/F5), but requires a connection to a PC.
Steps:
- Enable USB debugging on your phone: Settings → About Phone → MIUI Version (click 7 times) Settings → Additional → For Developers → Debugging on USB

- Enter the command to check the connection: adb devices (should appear serial number of your Xiaomi).
- Remove Outlook by command: adb shell pm uninstall --user 0 com.microsoft.office.outlook

Method 3: Disconnection via MIUI Hidden Settings
MIUI 12-14 and HyperOS have a hidden menu for managing system applications, which allows you to disable (but not remove) Outlook without ADB:
- Open the phone app and type in: ##4636###
- Select Phone Information → Settings menu (or Usage statistics).

Method 5: Reset to factory settings (extreme case)
If Outlook came after the MIUI update and isn't deleted by other means, you can do a hard reset.
- 🔄 Delete all data from the phone (photos, messages, applications).
- 📱 It will return the firmware to factory status, but it does not guarantee that Outlook will not return after the first update.
- ⚙️ On some models (Xiaomi 13 Ultra, Mix Fold 3) reset may bring back the old version MIUI.
How to reset:
- Make a backup through Settings → About Phone → Backup.
- Go to Settings → About Phone → Resetting → Delete all data.
