We’re aware of an issue currently affecting some Plusnet customers when sending emails to Microsoft-owned domains such as Hotmail, Live, and MSN. Customers may receive a bounce-back message stating:
“A message that you sent to the following recipient could not be delivered due to a permanent error"
We understand how frustrating this can be and want to reassure you that our teams are actively investigating the issue. Early indications suggest the problem may be related to Microsoft’s email systems, and we are working closely with them to identify and resolve the issue as quickly as possible.
We appreciate your patience and will provide updates as soon as more information becomes available.
Update 15/07/2025
We're aware that some customers are still seeing delivery failures when sending emails to multiple recipients with Microsoft-owned domains. As the original issue has been resolved, a new support ticket has been opened to investigate this specific problem.
