This KB Article provides the initial steps to add your account to Microsoft Outlook for the first time.
At the Welcome to Microsoft Outlook prompt, click Next.
At the Microsoft Outlook Account Setup prompt, leave the radio button selected to Yes and click Next.
At the Add Account prompt, Your Name and E-Mail Address will automatically populate. Click Next.
You will then be prompted to multifactor authenticate using Duo. Please see Duo Security for more information.
Finally, click Finish.
Outlook will then begin the process of syncing your mailbox content, calendars, contacts, and settings from the cloud. Depending on the size of your mailbox, this will take some time.
