According to Nintex Support Case #00502834
We need the implementation of the email trigger functionality using the OAuth authenticator for Email configuration on the Nintex Kryon server to meet the Serpro client's need.
For this, we thought that the option to select "Exchange 2007 and above (EWS)" as the server type could be repeated in the Email Settings module, which is already present in the email trigger solution and also present in the advanced command for sending email.
Great feedback, thank you!
As part of the Email ACs to DACs project, we'll align the experience of all email migrations in the product.
