Delivery Status Notification (Failure)‏ in Outlook

[HighRabbit]

What's up guys. I have two aliases in my Outlook account - Erik.Murin and Murin.Erik. I can send anything to anyone from Murin.Erik, but when I send something using Erik.Murin, it shows me over 500 the same emails in sent folder, none of them are actually sent and after a while I get the:

 

"This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed."

What should I do? I have tried to contact MS, but they do and tell me nothing. That Erik.Murin@outlook.com is important for me as I have lots of work to do using that email, it's on my Windows 10, Amazon and etc. Maybe I should delete that Outlook account and then create it again with the same address? Would that work?
