Learn more details about this error and how you can troubleshoot it.
You may receive the message "We have found a virus on your attachment...Send your email again...ML0021" because the AOL email virus scan detected a virus on the file you’re attempting to send as an attachment.
Once a file has been rejected by the AOL email service as containing a virus, it can’t be sent even if the virus is cleaned by a virus scan on your computer. You’ll need to use another email service to send your file to the intended recipient.
