How to Change Your Password in Outlook (Web, Desktop, and Mobile)

Changing your Outlook password can mean two different things, and that’s where most confusion starts:

  1. Changing the password for your Microsoft / email account itself (so no one can log in with the old one anymore), or
  2. Updating the saved password inside the Outlook app (after you’ve already changed it elsewhere so Outlook stops asking you to sign in).

Both are related, but they’re not the same. Outlook is usually just a mail client that connects to an email account (Microsoft 365, Outlook.com, Gmail, work email, etc.). You normally change the password on the account, not inside the app.

Below, we’ll walk through:

  • What “changing your Outlook password” actually means
  • How to change passwords for different Outlook setups
  • Why steps differ between web, desktop, and mobile
  • What you need to check in your own setup

1. What “Change Password on Outlook” Really Means

When someone says “change my Outlook password,” they may be talking about:

  • A Microsoft account password
    Used for Outlook.com, Hotmail, Live.com, and Microsoft 365 personal accounts.

  • A work or school account (Microsoft 365 / Exchange)
    Managed by your company or school’s IT. Changing this password can affect email, Teams, OneDrive, and more.

  • A non-Microsoft email in Outlook
    For example, Gmail, Yahoo, iCloud, or custom business email you’ve added to Outlook. The password is changed with that email provider, then updated in Outlook.

  • An app-specific password
    Some services (like older Gmail setups or accounts with extra security) use “app passwords” that are different from your main account password.

So before clicking anywhere, it helps to answer:
“Am I changing the password for my email account, or just updating Outlook so it uses my new password?”


2. Step-by-Step: Changing Your Microsoft / Outlook.com Password

If you use Outlook.com (or an email ending in @outlook.com, @hotmail.com, @live.com, @msn.com) or a personal Microsoft 365 account, your password is tied to your Microsoft account.

2.1 Change Your Password in a Browser

  1. Open a browser and go to Outlook.com.
  2. Sign in with your email and current password.
  3. Click your profile picture / initials in the top-right.
  4. Choose “My Microsoft account” (or similar wording).
  5. In your account page, look for “Security”.
  6. Under Security, find “Password” or “Change my password”.
  7. Confirm your identity (via email code, SMS, or authenticator app if enabled).
  8. Enter your current password, then your new password twice.
  9. Save the changes.

From now on, every app that uses that Microsoft account (Outlook desktop, Outlook mobile, OneDrive, etc.) expects the new password.

2.2 Update Outlook Apps After Changing It

Often you don’t have to do anything—modern Outlook apps usually re-authenticate automatically. If they don’t:

  • If prompted, enter your new password when Outlook shows a sign-in window.
  • If it keeps failing, you may need to remove and re-add the account in Outlook (more on that below).

3. Changing a Work or School (Microsoft 365 / Exchange) Password

If your Outlook email is something like [email protected] or @school.edu and you log in via Microsoft 365:

  • Your password is usually controlled by your organization’s IT.
  • Changing it can affect multiple services: Outlook, Teams, SharePoint, VPN, etc.

3.1 Common Ways to Change It

Depending on how your organization is set up, you might:

  • Use a special password change page (often linked from your company intranet).

  • Use Office.com:

    1. Go to office.com and sign in.
    2. Click your profile picture > “My account” or “View account”.
    3. Look for Security or Password and follow the prompts.
  • Use Ctrl + Alt + Delete on a Windows work PC and choose “Change a password” (if joined to a company domain).

After you change it, Outlook on your work devices will usually show a prompt saying your password has changed and ask you to sign in again.

Policies vary a lot here. Some organizations require specific password rules, multi-factor authentication, or periodic forced changes.


4. Changing Password for Another Email Provider in Outlook

Many people use Outlook to access Gmail, Yahoo, iCloud, or a custom business email. In that case:

  • You do not change the password in Outlook first.
  • You change it on the email provider’s website, then update Outlook if needed.

4.1 The General Pattern

  1. Go to your email provider’s website (e.g., gmail.com, yahoo.com).
  2. Sign in with your current password.
  3. Find the Account / Security / Password section.
  4. Change your password there.
  5. Open Outlook (desktop, web, or mobile).
  6. When Outlook says it can’t sync or asks you to sign in, enter the new password.

For some providers (notably Gmail with extra security turned on), you might need an “app password” specifically for Outlook rather than your main account password.


5. Updating Saved Passwords in Outlook Desktop (Windows & Mac)

Sometimes your account password is already changed, but Outlook desktop is still trying to use the old one, causing repeated sign-in errors. The solution depends on version and account type, but it usually follows this logic:

5.1 For Modern Microsoft Accounts (Most Users)

If your account is a modern Microsoft 365 or Outlook.com login:

  • Outlook typically uses a web-style sign-in window (it looks like a webpage, not a small plain dialog box).
  • When the password changes, Outlook will:
    • Show a popup like “Need password”
    • Ask you to sign in again via the web-style window
    • Let you enter the new password

You rarely need to manually type the password into a settings screen.

5.2 If Outlook Keeps Failing to Sign In

On Windows Outlook desktop (Microsoft 365 or Outlook 2019/2021):

  1. Open Outlook.
  2. Go to File > Account Settings > Account Settings.
  3. Select the problematic account.
  4. You can try “Repair” if available. Outlook will re-check your login and often prompt you to sign in again.
  5. If that fails, remove the account:
    • Select the account > Remove.
    • Then choose Add Account and sign in fresh with the new password.

On Mac Outlook:

  1. Open Outlook.
  2. Go to Outlook > Settings > Accounts.
  3. Select the account.
  4. If possible, click to re-authenticate or sign in again.
  5. If it keeps failing, remove the account and add it again with the updated password.

Removing the account from Outlook doesn’t delete your email from the server; it just clears the local setup and lets you start over with the correct credentials.


6. Updating Passwords in Outlook Mobile (iOS & Android)

On phones and tablets, Outlook is often tightly tied to the cloud, so you usually don’t see a manual “password field” in settings.

6.1 When Your Password Changes

If you change the password for an account that’s used in Outlook mobile:

  • Outlook will usually show a banner or error saying it can’t sync.
  • Tapping that alert typically brings up a sign-in screen.
  • You sign in with your new password (or app password, if your provider requires one).

6.2 If It Still Won’t Connect

You can:

  1. Open the Outlook app.
  2. Go to Settings (gear icon).
  3. Under Mail Accounts, tap the account.
  4. Look for options like Re-enter password, Re-authenticate, or Fix account.
  5. If those don’t work, remove the account from Outlook mobile and add it again using the new password.

Different email providers may open their own sign-in pages inside Outlook (for example, Gmail’s Google sign-in window), so the exact screens vary.


7. Security Tips When Changing Your Outlook-Related Password

Regardless of which type of Outlook setup you have, a few best practices always help:

  • Use a strong password
    Mix upper and lower case letters, numbers, and symbols, and avoid obvious words or dates.

  • Turn on multi-factor authentication (MFA)
    This means you need something more than just the password—like a code from an app or SMS—to sign in, making it much harder for attackers to access your email.

  • Watch for suspicious devices or sessions
    Many account security pages show where you’re signed in. If you see devices or locations you don’t recognize, sign them out and consider changing your password again.

  • Avoid reusing passwords across services
    If one site is compromised, reused passwords can let attackers access your email, which they can then use to reset other accounts.

How strict you need to be depends heavily on whether this is a personal hobby email, a critical work account, or an account that holds sensitive data.


8. Why the Exact Steps Differ So Much

The process isn’t identical for everyone because several variables change how you “change your Outlook password”:

VariableHow It Changes the Process
Type of accountMicrosoft personal, work/school, Gmail, Yahoo, custom domain all have different portals.
Where you read emailWeb (Outlook.com), Windows desktop, Mac desktop, iOS, Android each have their own flows.
Authentication methodPlain password vs. app password vs. SSO (single sign-on) changes where you update it.
Security settingsMFA, corporate policies, password complexity rules can add extra steps.
Administrator controlWork/school IT might restrict how/where you can change passwords.

For example:

  • A home user with Outlook.com on a Windows PC usually just changes their Microsoft account password online and signs in again when Outlook asks.
  • A corporate user may have to follow an internal password change policy and then wait for Outlook on multiple devices to update.
  • Someone using Outlook to read Gmail will change their password in Google’s account settings first, then fix Outlook when it complains.

9. Finding the Right Approach for Your Own Setup

The key to changing your “Outlook password” cleanly is to first clarify:

  • What kind of email address you’re using (Microsoft, work/school, Gmail, something else).
  • Where you normally change passwords for that account (Microsoft account page, company portal, Google account settings, etc.).
  • Which devices and apps are connected (desktop Outlook, web Outlook, mobile Outlook, other mail apps).

Once you know those pieces, the right path becomes clearer: you change the password with the account’s provider, then let Outlook catch up and re-authenticate, updating or re-adding the account only if it doesn’t adjust on its own.

The exact screens, buttons, and prompts you’ll see depend on this personal mix of account type, security settings, and apps, which is why your own setup is the final missing piece in how you’ll change your password in Outlook.
