Outlook group email stops working since 26 Jun 2022
I have a group email address working for more than 6 months but all of a sudden emails cannot be delivered since last weekend. I'm getting below error code: Delivery has failed to these recipients or groups: mailto:email address removed for privacy reasonsThe recipient's email system isn't accepting messages now. Please try resending your message later or contact the recipient directly.
