This topic applies to Office 365 Enterprise, Office 365 Business Essentials or Office 365 Business Premium.
User passwords expire on a regular basis in Office 365. Global and delegated admins can make the user’s password expire after a certain number of days or set the password to never expire. Admins can also change the number of days before users are notified of password expiration.
- Sign in to Office 365 with your work or school account.
- Go to the Office 365 admin center.
- Go to Service settings > Passwords.
- If you don’t want users to have to change passwords, select Passwords never expire. If you select this option, users won’t get any reminders anymore to change their passwords.
- If you want user passwords to expire, type the number of days before the password should expire. Choose a number of days from 14 to 730.
- Type the number of days before users are notified that their password will expire, and then click Save. Choose a number of days from 1 to 30.

It is good practice to change email passwords occasionally. Sometimes, ComStat may ask you to change passwords if we suspect that a third party has compromised your account. If users do not know passwords, we can force a password change, however you should take responsibility of your passwords and we ask users to log in to their email accounts and overwrite our forced password changes with passwords of their own. To manage your passwords:
1. Go to your Webmail control panel at http://webmail.example.com (replace example.com with your own domain name).
2. Login with your email address and the password if you know it, or the password we have given you. Click open the settings icon. The image below shows you where this icon is.
This is your Webmail account, and you can use this control panel to manage your email and your email settings, review mail statistics, and more.
3. In the next screen check that the control panel is opened to the “Account Settings” preferences, and the “User” tab, and then input your passwords and click save. A time of writing you will need a capital letter and a number in your password. Our policy may change from time to time. When you have entered your passwords, click “save”, which is located above the “User” tab.
You have now changed your password. Also, changing your password will mean you need to update settings on any devices that connect to Office 365, including desktops, laptops, tablets, or mobile phones. This process will allow you to manage one account at a time. To manage another account, log out of your Webmail account, and then log in to the next account with that user’s credentials, and repeat.
