When sending email to an AOL account through Outlook (any version) and through multiple email accounts going through our company email server, we get the error code 521 5.2.1 : AOL will not accept delivery of this message
None of the accounts have "AOL" in their description and we have tried several ports for the outbound setting. When sending using Mac Mail on the same computer as outlook, or sending directly through our mail server interface, the email goes through to the AOL recipient. OUr mail server people say it is nothing to do with their system, but I question that at this point. It either has to be something caused by outlook or something on our server settings. Any thoughts?
