Change your password in Office 365 for business
When you first sign in to Office 365 for business, use the temporary password given to you, and then create a new password to use for sign-in from then on. You can also change your password at any time after you have signed in.
Change my password
Go to Settings > Office 365 settings > Password.
Type your old password, and then type a new password and confirm it.
Some users can’t change their password in Office 365 because their organization creates and maintains their accounts. If you don’t see a link to change your password on the Password page, you can’t change your work or school account password in Office 365. Your organization might have sent you instructions to help you change your password. Follow those instructions to change your password, or ask your admin for help.
For more information, see Change the password for your work or school account.
Note When you change your password for yourwork or school account , be sure to update the password on your phone and desktop email program to match the new password for your account.
I forgot my password, or it no longer works
If you’ve forgotten your password or it’s no longer working, use the Microsoft Online Password Reset site to send a new password request to your workplace technical support—typically the person who set up your work or school account for you.
If you want to contact your workplace technical support team directly, send them a link to the admin help topic Reset a user's password.
