If you’re among the many users who rely on access to your Office 365 e-mail by using a mobile device or desktop e-mail program, here’s some information that will help you keep your mobile device and desktop e-mail program connected to your Office 365 account.
This information applies to Android, BlackBerry, iPhone, IPad, iPod Touch, Nokia (Symbian), Windows Phone, and Windows Mobile devices. It also applies to desktop e-mail applications you may be using including Apple Mail, Mozilla Thunderbird, Microsoft Outlook, or Windows Live Mail.
The Office 365 service includes a password expiration policy that requires you to periodically change your password. Although this policy seems like a hassle, it helps protect the information in your e-mail account. Most Office 365 password policies require you to change your password every 90 days. This setting for your password may be more often or less if it’s been changed by the person who manages your e-mail account. It can even be set up to never expire.
A problem occurs when the e-mail account password that you entered on your mobile device or desktop e-mail program doesn’t match the current password for your account. So, if you allow your Office 365 password to expire, your mobile device or desktop e-mail program won’t be able to connect to your account. Similarly, if you change the password on your account without changing it on your mobile device or desktop e-mail program, your mobile device or desktop e-mail program won’t be able to connect.
Glad you asked—two things. You need to make sure that your Office 365 password doesn’t expire by regularly changing your password. You also need to make sure that the password that you entered into the e-mail account settings on your mobile device or desktop e-mail program matches your current Office 365 account password.
