AT&T’s email servers are blocking connections from Microsoft 365 due to a “high volume” spam wave. Customers are unable to receive emails from Microsoft 365 addresses, leading to multiple complaints on AT&T forums. AT&T attributes the issue to spam originating from Microsoft’s servers and is collaborating with Microsoft to address the problem.
Key takeaways from the meeting notes:
– AT&T’s email servers are currently blocking connections from Microsoft 365 due to a “high volume” spam wave originating from Microsoft’s service, causing a mail delay.
– AT&T customers are unable to receive emails from Microsoft 365 email addresses, and when attempting to send emails to @att.com, @sbcglobal.net, or @bellsouth.com addresses, the AT&T servers are refusing the connections.
– Reports indicate that this issue may also be affecting Gmail, with users reporting difficulties sending emails to AT&T addresses from both Microsoft 365 and Gmail accounts.
– AT&T has acknowledged the issue and attributed it to an industry-wide problem of unusually high spam volume originating from Microsoft’s servers.
– There was an attempt to gather more information on the spam campaign from Microsoft and Gmail, but no response was received at the time of the publication of the meeting notes.
– Both Microsoft and Google have implemented or plan to implement measures to address spam, including daily email limits for external recipients and stricter spam thresholds and authentication guidelines for bulk email senders, respectively.
These takeaways outline the current issue, the impact on AT&T customers and potential implications for Gmail users, as well as the responses from AT&T, Microsoft, and Google in addressing the spam problem.
