I have a service account that I need to skip the Okta login altogether. I have my AAD federated so all activity get redirected to login via Okta. We have a SharePoint service account (noreply@...) that needs to just login and send the stupid email. It fails because it is prompted to login to Okta. I'm not even talking about MFA. I need it to bypass the login altogether.

I found one article that says to change the service account to the "onmicrosoft.com" domain. Trying that first but wanted to see if anyone had other suggestions?

Any suggestions?
