I have been having the same problems with both of my Outlook/Hotmail accounts for the past few days. Whenever I try to send an e-mail, I get an automated email from *** Email address is removed for privacy *** saying:

"This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed."

I am unable to send messages and the recipients of these e-mails have confirmed that they did not receive anything from me.

I don't know what to do about this issue and would really appreciate some help.
