Cannot send messages using the server iCloud.

Trying to send an email and keep getting the following error - "Cannot send message using the server iCloud. The sender address XXXXXX@me.com was rejected by the server p38.smtp.mail.me.com. The server response was: Authentication required prior to MAIL/SAML/SEND/SOML. Select a different outgoing mail server from the list below or click. Try Later to leave the message in your Outlook until it can be sent."

How can I fix this?

Best,

Outgoing server for my email address is set to iCloud I removed my email account and set it up again, now the outgoing server is set to iCloud and I cannot send emails anymore. I tried to add another SMTP outgoing server with my email providers data, it connects (connection doctor says) but won't send emails, because "The server response was: Authentication required". Any ideas how to fix this? It is the same email address I use as my apple ID.
