Who is your email provider? If you are unsure what is the part of your address after the @ sign?
You need to use outlook.com or an Exchange account to sync calendar and contacts with the devices. If you use pop or imap, you need to use a sync utility, such as gsyncit to sync calendar & contacts with devices. Or, for iOS, use the iCloud add-in with classic outlook.
