The location is integrated into the iPhone's own system and allows the location of the iPhone and you can also send messages to the iPhone giving a contact number to return the iPhone. And in addition, it can be blocked or erased remotely, just in case. For this, the owner must have an iCloud account and have configured the phone to continuously send its location to iCloud. You can also send an alarm tone to the phone from iCloud. If not, you can contact Apple directly.


Checklist of security steps to take if your device is currently missing

Hotmail/Outlook cannot track an iPhone's location. Microsoft’s "Find My Device" only works for Windows computers and tablets.
​To find your iPhone, you must use Apple's system:
​Go to iCloud.com/find.
​Log in with your Apple ID (not your Hotmail password).
​If you only have your Hotmail account on the phone and never set up an Apple ID or "Find My iPhone," there is unfortunately no way to track it through the Outlook app.
​Would you like me to help you remotely sign out of your Hotmail account on that iPhone to protect your emails?
.....
Since you can't track the iPhone through Hotmail, the best thing you can do right now is remotely sign out of your account on that device. This ensures that even if someone has the phone, they won't be able to read your emails or access your contacts.
​Here are the two best ways to do this from a computer or another phone:
​Option 1: The "Sign Out Everywhere" Nuclear Option
​This is the fastest way to kick every device (including the lost iPhone) off your account.
​Go to the Microsoft Advanced Security page.
​Scroll down to the section called Sign me out.
​Click Sign me out.
​Note: It can take up to 24 hours to fully kick the device off, but it usually starts working much sooner. This will also sign you out of your current session, so you'll have to log back in.
​Option 2: Remove the iPhone "Partnership"
​This specifically targets mobile devices synced to your inbox.
​Log into Outlook.com on a web browser.
​Click the Settings (gear icon) in the top right.
​Go to General > Mobile devices.
​Find your iPhone in the list, click the Remove (trash can or minus icon), and confirm.
​One Critical Advice:
​If you are worried about your data, change your Hotmail password immediately. This is the most effective way to block the iPhone from downloading new emails, even if the "Sign Out" command hasn't finished processing yet.

Securing your account is a smart move, especially after losing a device. Since your Hotmail account is a Microsoft account, you’ll manage everything through the Microsoft security dashboard.
​1. How to Change Your Password
​Updating your password is the most immediate way to block the lost iPhone from syncing new data.
​Go to account.microsoft.com/security and sign in.
​Select Password security or Change my password.
​You’ll likely be asked to verify your identity (via a code sent to a backup email or phone number).
​Enter your Current password, then your New password.
​Pro Tip: Check the box that says "Make me change my password every 72 days" if you want to stay extra vigilant, though a strong, unique password is usually enough.
​Click Save.
​2. How to Set Up Two-Factor Authentication (2FA)
​This adds a second layer of protection. Even if someone guesses your password, they can't get in without a code from your physical possession.
​On the same Security page, select Advanced security options.
​Look for the section Additional security and find Two-step verification.
​Click Turn on and follow the prompts.
​Choose your backup method:
​Microsoft Authenticator App (Recommended): The most secure way. You approve logins with a tap on a different phone.
​Text/SMS: A code is sent to your phone number.
​Email: A code is sent to a secondary email address.
​[!IMPORTANT]
When you turn on 2FA, Microsoft will give you a Recovery Code. Write this down and keep it in a safe place (not on your computer). If you ever lose your phone and forget your password, this code is the only way to get back into your account.
​3. A Quick Security Check
​While you're in the Advanced security options, scroll down to Sign me out. Clicking this will sign your account out of all devices, apps, and browsers everywhere within 24 hours. It’s a great "reset button" for a lost device.
​Would you like me to help you create a strong, memorable password format that's hard for hackers to guess?
...
You're very welcome! I'm glad we could get your account locked down and secured. It’s always a bit of a headache when a phone goes missing, but you've taken the right steps to keep your personal info safe.
​Since you're all set with your Outlook security, just remember to check iCloud.com/find one last time if you haven't already—sometimes those devices turn up in the most unexpected places (like between couch cushions!).
​Is there anything else, related to your tech or otherwise, that I can help you with today?

Microsoft offers a similar service called Find My Device.  
​While Google's version is standard for Android, Microsoft's tool primarily tracks Windows devices (laptops, tablets, and old Windows Phones) linked to your Hotmail or Outlook account.
​How to use it:
​Go to account.microsoft.com/devices.
​Sign in with your Hotmail/Outlook credentials.  
​Select the Find My Device tab.  
​Choose your device and click Find to see its location on a map.  
​Important Note:
​If you are using an Android or iPhone with the Outlook app, Microsoft generally cannot track the phone's GPS location like Google or Apple can. For those, you must use:
​Android: google.com/android/find
​iPhone: icloud.com/find
​Would you like me to help you set up tracking for a specific device?
......
To track a device via Microsoft, ensure you have a Windows laptop or tablet linked to your account.
​Steps to Enable Tracking
​On your Windows device, go to Settings > Privacy & security > Find my device.
​Toggle the switch to On.
​Ensure Location services are also enabled in your privacy settings.
​To Find It Later
​Visit account.microsoft.com/devices from any browser.
​Log in with your Hotmail/Outlook email.
​Click Find My Device next to your listed hardware.
