Hi Microsoft, 

When sending email we get the following error for our account bsesindia.com hosted on domains.live.com for each of the email in To, CC and BCC.

501 5.5.4 Invalid Email Address

After waiting for long hours or few days the error is automatically resolved.

Can you let us know what is the issue? I have double checked and the emaisl are all fine.

Rgrds,
Ojal

In Outlook an email was sent with an invalid email address. Repeatedly 5.5.4 Invalid Email address message is received in Errors. How do I stop receiving the 5.5.4 Invalid Email address message?
