need help with sending emails

Question

WE are having issues with the outlook email with sending emails. Need a call as soon as possible to be able to remote access and solve issue.

Answer 1

Based on the error, you are using a corporate email account, correct?

Your account may have been compromised or blocked due to excessive email sending (mass spam). Only the IT Administrator can verify if the account has been compromised and unblock it. The administrator can follow the steps in the link below. Therefore, you should contact your company's IT administrator.

Answer 2

This is the Error I receive,

• If the user tries to send email, the message is returned in a non-delivery report (also known as an NDR or bounce message) with the error code Fix error code 5.1.8 in Exchange Online and the following text:

"Your message couldn't be delivered because you weren't recognized as a valid sender. The most common reason for this is that your email address is suspected of sending spam and it's no longer allowed to send email. Contact your email admin for assistance. Remote Server returned '550 5.1.8 Access denied, bad outbound sender."
