User passwords expire on a regular basis in Office 365 Small Business. As an admin, you can set a policy to make a user's password expire after a certain number of days. Users are notified to change their password starting 14 days before password expiration.
Note Prior to November 1st 2013, the Office 365 portal could only set the password policy in the default onmicrosoft.com domain. You can now use the Office 365 portal to make password policy changes to all domains. If you made password policy changes prior to November 1st, we recommend that you set the policy again to apply the policy to all of your custom domains.
