Step 1: Open the Outlook application and select File > Add Account.
Step 2: On the next screen, enter your email address, select Advanced options, then check the box for Let me set up my account manually and select Connect.
Step 3: Select your account type. Most of the time when you need to use this option, you'll select IMAP.
Step 4: The Account settings screen should be pre-populated with most of the account settings you need. However, if you need to look up your settings, see the POP and IMAP account settings topic. Enter your incoming and outgoing server settings and then select Next.
Step 5: Enter your password and then select Connect.
If you are unable to connect, double-check the account settings. 99% of the time the issue is a simple typo or entering a wrong setting.
