MONITORING

We are continuing to closely monitor the ongoing Microsoft 365 service incident. Our Continuity Service is once again operating completely stably, and all email security and filtering systems continue to run normally without disruption. While Microsoft’s servers are accepting inbound traffic from our gateways, some Outlook clients may still experience residual delays when displaying or retrieving newly delivered messages as Microsoft completes its recovery. https://status.cloud.microsoft/m365

Description

Timeframe: 30.11.2026–10:00–12:00 CET Affected services: Spam and Malware Protection, Email Encryption What changes: From 30.11.2026 10:00 CET, SMTP authentication for outbound messaging will only be offered on secure connections that meet our minimum security criteria: Connection: secured with TLS before authentication Protocol and ciphers: as listed in the TLS chapter of the Control Panel administrator manual under https://cp.hornetsecurity.com/manual/index.html#encryption_module/c_tls.html. These TLS requirements are the same as those that already apply to encrypted connections to our relay today. The only change is that authentication is no longer offered until a TLS connection that meets our security requirements has been established.
