If you have configured the autodiscover DNS records, then configuring Outlook to connect should is very simple. This guide applies specifically to Outlook 2010/2013/2016, however other editions should be very similar.
On your computer, navigate to the Control Panel, and then Mail. Create a new profile and give it a name. Enter your Name, email address and password, then click next.
Outlook will search for the server to connect to (using the autodiscover DNS records described above). You may receive a message that the server is trying to configure your email account – click yes to this box to allow the process to complete. You will be asked to enter your username and password. Remember that your username will be your email address, and your password will have been provided when your mailbox was configured. Tick the option to remember the password so you do not need to enter it every time you open Outlook.
When finished, in the Mail dialogue box set the option to ‘Always use this profile’ and select the newly created profile in the dropdown menu.
