Recipient does not Receive Emails Successfully Sent via Graph API sendMail. Why not?

Question

My windows daemon successfully sends emails via the graph API (code below). However, xxx.williams@outlook.com does not receive them. Why not?

• I, xxx.williams@outlook.com, have an active MS 365 Apps for Business license and am the admin.
• sendMail has application permissions along with all other mail and mailbox permissions.
• xxx.williams@outlook.com junk mail folder is empty

returns:

============ SEND MAIL =================

OK

{"@odata.context":"https://graph.microsoft.com/v1.0/$metadata#users/$entity","businessPhones":["7815073118"],"displayName":"XXXWilliams","givenName":"XXX","jobTitle":null,"mail":null,"mobilePhone":null,"officeLocation":null,"preferredLanguage":"en","surname":"Williams","userPrincipalName":"XXxxWilliams@Xxx.onmicrosoft.com","id":"xxxxxxxx-58c0-42a6-9203-06eec6882b5c"}

What is broken?

 

Answer 1

Your graphapi call is getting the user profile, not sending an email message. Also no content is sent with the get method, only headers.

from the response display it seems to be working correctly. To send mail see
