Office 365 Password Expiration Policy

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.

  1. Sign in to Office 365 with your work or school account.
  2. Go to the Office 365 admin center.
  3. Go to Service settings > Passwords.
  4. 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.
  5. 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.
  6. 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.

Password security

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 you have forgotten your password, we can force a password change.

Users are responsible for their passwords at all times. If we force a password change, users should log in to their email accounts and overwrite forced password changes with passwords of their own. Good passwords include:

  • 8-15 characters
  • Capital letters
  • Numbers
  • Special characters

Email passwords cannot be changed using your desktop version of Outlook. To change your email account password, login to your Office 365 online control panel with your email address and existing password with a web browser like Internet Explorer, Firefox, or Chrome.

There is more than one way to change passwords in Office 365. For instance, users can log into http://portal.office365.com and locate settings from the portal home page. Users are familiar with Outlook Web Access, so the tutorial here should be a convenient method.
