  • I am have not gotten this working, to be honest,  I am pretty lost on what the steps are.  The instructions for 1&1 internet do not match what I am seeing in their interface.

  • Hi HoPZ,

    In this situation,I recommend checking the DNS records.You can check your domain records via .

    Add your domain to Office 365 without redirecting your name server records to Office 365

    If you are a small business user,we recommend changing your domain's Name Server records to point to Office 365.References as below.
