Reset Your Office 365 Password or Unlock Account

To reset a password on Office 365, select the forgotten-password option on the Microsoft sign-in screen and verify your identity using a method already registered to the account. To unlock an Office 365 account, follow the security-code or password-reset prompts shown during sign-in; work and school users may need their administrator if self-service recovery is unavailable.

What do you need before resetting an Office 365 password?

First, identify whether you use a personal Microsoft account or an account issued by a workplace or school. The recovery process and the person who controls the account are different.

Have the following information ready:

• The complete email address or username used with Office 365.
• Access to a registered recovery email address, phone, authenticator app, or security key.
• A device and location you have used with the account before, especially if personal-account recovery requires additional checks.
• For a work or school account, the organization name and contact details for its help desk or Microsoft 365 administrator.

A verification method is a previously registered way to prove that the account belongs to you. Microsoft or your organization decides which available methods appear. Never give a verification code or password to someone who contacts you unexpectedly.

How do you reset your Office 365 password?

Use these steps if you forgot your Office 365 password or cannot sign in:

1. Open the company’s official website and select Sign In.
2. Enter the email address or username connected to Office 365 and continue to the password screen.
3. Select “Forgot password?” or “Can’t access your account?” The exact wording can differ between personal and organizational accounts.
4. For a work or school account, complete the anti-automation check if one appears. For a personal account, choose where Microsoft should send a verification code.
5. Complete the offered identity check. An organization may require more than one verification method.
6. Enter the code or approve the request, then create a new password that meets the rules shown on the screen.
7. Sign in again with the new password. Update the saved password in Outlook, Teams, mobile mail, and other Office apps that keep requesting the old one.

Work and school self-service password reset works only when the organization has enabled it and you previously registered the required security information. If the page says to contact your administrator, the reset cannot be completed through that self-service screen.

How do you unlock a locked Office 365 account?

An Office 365 account is locked when the sign-in screen specifically reports a lock, block, or temporary restriction. A message saying only that the password is incorrect does not necessarily mean the account is locked.

To unlock a locked Office 365 account:

1. Try signing in through the official Microsoft sign-in screen.
2. Read the message carefully and select the displayed recovery, verification, or password-reset option.
3. Complete the requested identity check. A personal Microsoft account may ask for a security code. A work or school account may offer self-service password reset using registered security information.
4. Change the password if prompted, then try signing in again.

If a personal account shows a reinstatement option instead of the normal security-code process, use the form offered directly in that sign-in message. If a work or school account remains locked after successful verification, contact the organization’s administrator. Do not repeatedly guess passwords, because organizational security rules may continue blocking sign-in attempts.

What if Office 365 self-service recovery does not work?

For a work or school account, contact the internal help desk, school technical-support team, Microsoft 365 administrator, or the person who originally issued the account. An administrator may need to reset the password, unlock the user, update authentication methods, or confirm that self-service password reset is enabled.

Provide the administrator with:

• Your name, organization, and complete work or school username.
• The exact error message, without including your password or verification codes.
• The approximate time of the failed sign-in and the Office app or browser involved.
• Whether you can still access a registered phone, email address, authenticator app, or security key.

For a personal Microsoft account, use Microsoft’s Sign-in Helper when no listed verification method is recognizable or accessible. Microsoft support cannot bypass account security, reveal a password, or manually change protected account details merely because someone requests access.

How do you contact official Office 365 support?

Open the company’s official website and choose the support or contact option that matches the account:

• Personal account: Use the Microsoft Sign-in Helper for access problems. For other technical issues, enter the problem in Microsoft Support and select Get Help; available contact options are shown there.

• Work account: Contact your employer’s help desk or administrator first. A Microsoft 365 administrator can use Help & support in the Microsoft 365 admin center when Microsoft assistance is required.

• School account: Contact the school’s technical-support team or account administrator. Microsoft directs non-administrator organizational users back to their organization for password and lockout help.

Do not trust an unsolicited caller or message claiming that payment, remote access, or disclosure of a verification code is required to recover an Office 365 account.

How do you protect an Office 365 account after recovery?

1. Review the account’s security information and replace recovery methods you no longer control.
2. Add another permitted verification method so one unavailable phone or email address does not leave you without an option.
3. Enable two-step verification or multifactor authentication when the account or organization makes it available. This requires an additional identity check beyond the password.
4. Review recent sign-in activity and check the device, browser, application, and approximate location for entries you do not recognize.
5. If activity appears unauthorized, change the password again and report the incident to the workplace or school administrator when applicable.
6. Sign out of unfamiliar devices and update stored credentials in trusted Office apps.

Use a unique password that is not shared with another service. An Office 365 password reset restores access, but reviewing recovery details and sign-in activity helps prevent the account from being taken over again.
