Hello MarilynN&Sarah
Just to clarify a couple of things raised in your description
#1 - Outlook does not sync with a device. It sync's data with the <email account> server
#2 - The protocol that can be used to connect to a given email account is governed by the email service provider (ESP) . Unless you have a hosted Exchange account or using Outlook.com for which you can use Exchange when configuring the account, you would be limited to either IMAP or POP3.
A quick overview of the protocols (Exch, IMAP, POP3)
#3 - Exchange - bi-directional sync of all items (i.e. mail, contacts, calendar etc)
#4 - IMAP - a bi-directional sync of all email items (contact/calendar data is lccal only to the device and do not sync with the server)
#5 - POP3 - a one-way one-time download of the <Inbox> folder
So to get back to your question
#6 - Without knowing your ESP, am going to assume that they support IMAP for the email account (any major ESP does). You would configure the account simply by entering the email address/password for the account and Outlook will automatically configure the account using IMAP
#7 - In order to be able to sync your contact/calendar data across all devices, would suggest creating /using free Outlook.com account and maintain your contact/calendar data in this account. Add the account to each of your devices and all will be able to share the data. Just need to configure it the same as your IMAP account - enter the email address/password and Outlook will automatically configure it as an Exchange account.
Your only option would be to get an Exchange account
