Hell0 I attempted to send an email to the following address: (removed PII). I received a message that Hotmail could not send this email because it was in the incorrect format. Correct the format or spelling to this format name@ hotmail.com. This email is correct and has been used for a long time. I was able to send this email by comcast.net with no problems.This is the only email address that I am having problems with at this time.
