I registered and created a new tên miền on Office 365 đồ sộ experience O365 E3 trial version then created an application in Dot Net đồ sộ send emails using graph API, both đồ sộ same and different (gmail etc.) domains.
On coding side I don't see any error being produced, however on mail box side immediately I receive an tin nhắn saying:

Delivery has failed đồ sộ these recipients or groups:
******@something.onmicrosoft.com
Your message wasn't delivered because the recipient's tin nhắn provider rejected it.

I am able đồ sộ send emails from mailbox, manually by visiting https://outlook.office.com/

    I am also having the same problem; Outlook/Hotmail emails are being rejected even by my own Hotmail trương mục - for instance when I try đồ sộ send an image đồ sộ myself for access on another device.
    I regularly receive notifiation that "Your message wasn't delivered because the recipient's tin nhắn provider rejected it", when sending new emails or even forwarding tin nhắn, not just with images but with text only messages.
    This occurs regularly when using my iPhone đồ sộ send Hotmail/Outlook emails, even with VPN switched on.
    What's the solution?

    I am getting the same error, it worked two days ago and I have not changed any settings.

    My tin nhắn ends with a hotmail.com

    the message is "your message wasn't delivered because the recipient's tin nhắn provider rejected it"

    I have checked the forwarding setting but this is more of a third các buổi party sending emails through my tin nhắn (that software is QuickBooks)

    it seems lượt thích there may be an added security that was recently turned on but I have no idea where

    Name : yourdomain.com
    Time : 3600
    Type : TXT
    Record : v=spf1 include:spf.protection.outlook.com -all
