Hi, we are a small company and we are having issues with Hotmail, Outlook, msn, or any Microsoft account. All our customers with Hotmail, Outlook, msn, or any Microsoft email address are not receiving any emails from us any more (they used to get our emails for years). The strange thing is we don't receive any bounced message or error message. It goes out from our end, but they never receive it. Everything appears to be fine on our end.
Can someone please shed some light as to I can do to resolve this ?
Your help will be most appreciated,
Thanks, Gary
