Organizing and accessing contact information in Outlook.com
Hello Joan,
If you set up your email as an IMAP or POP account, your calendars and contacts won't sync. You'll have you to add them as an Exchange ActiveSync account. Also, make sure that your email app has the correct permissions to access your calendar and contacts.
If your email account is working fine on a computer, the issue may be with your email app and you'll have to contact their support.
