Hello AranBit,
Thank you for reaching out to Microsoft Support!
It sounds like you're encountering an issue where emails sent to oneself using the Microsoft Graph API are not appearing in the Outlook inbox. This can happen due to several reasons:
- Junk Email Filters: Sometimes, emails sent to oneself can be filtered out as junk or spam. Check the Junk Email folder to see if the emails are being redirected there.
- Mail Flow Rules: There might be mail flow rules set up in your Exchange Online environment that are affecting the delivery of these emails. Verify if any rules are in place that could be moving these emails to other folders.
- API Permissions: Ensure that the application has the necessary permissions to send and receive emails. The permissions should include
Mail.Send
.
I have tested the Graph API in my tenant and able to see the mail in Inbox and Sentitems folder. Please check below.
Hope this helps.
