Hi do you have a documentation about how to set the azure apps and the correct rights ?
We have a customer which has setup the outbound mail with Microsoft Grpah we can send mail but when there is an attachement to the mail : pdf, doc then we have an error
IEmailUtilityGraph.SendEmailAsync() with attachments failed. Can't create new message Error message: Code: ErrorAccessDenied Message: Access is denied. Check credentials and try again.
thanks for your feedback
Rgds
