    Hi,

    You have posted in the Partner Center API forum, since your issue is related to SharePoint REST API I suggest you ask over at the dedicated SharePoint REST API forum over here:
    https://learn.microsoft.com/en-us/answers/topics/office-sharepoint-server-development.html

    (If the reply was helpful please don't forget to accept as answer, thank you)

    Hi @Shiv Sharma ,

    I tested to send email to distribution list using /_api/SP.Utilities.Utility.SendEmail, it will have such error:

    16394-image-1.png

    This is because of /_api/SP.Utilities.Utility.SendEmail is resolving based on user Principle, Distribution list is not the SharePoint user so cause the error, please check the blog for detailed information:

    One of the reasons of why sending email via client object model may not work in Sharepoint

    The workaround is that if you want to send email to multiple users, you can define a arrray for To like the code as attachment :
