For Mail Basic and Mail Business
This article lists several causes and solutions to resolve issues with the setup of email clients, such as Outlook, Apple Mail, or Thunderbird.
Missing Autodiscover Entry
If the automatic setup of the email account in Microsoft Outlook fails, first check whether an autodiscover record is created in the DNS settings of your domain. If necessary, create an autodiscover entry if no autodiscover entry exists for your domain.
You can find more information in the following article:
Wrong Username or Password
If you are asked for the username and password, check that the full email address is entered as the username in the account settings. Also, make sure that the correct password is entered. If necessary, you can change your password at any time. For more information, see the article Changing your email password.
Email Address is a Forwarding Address
Check whether your email address is a forwarding address. A forwarding address is an email address that forwards emails but does not have a mailbox function itself. Because the forwarding address only performs a forwarding function but cannot store messages or be used to send messages, forwarding addresses cannot be set up as accounts in an email program.
