We are currently investigating an issue with delays in email delivery for messages with server-side signatures sent by users in Australia.
- identified Sep 15, 2025, 11:31 PM UTC
The problem with delays in email delivery appears to be limited to a small subset of customers in Australia who may have experienced degraded performance of Microsoft 365 today. Our services are operating normally and the signatures are imprinted. We're monitoring the situation.

It looks like the incident affected only a handful of tenants in Australia East, and the overall impact was very limited and not related to CodeTwo. We’re not seeing any issues with our services, so we’re closing this incident. Our 24/7/365 Proactive Monitoring Team will continue to actively monitor the service. If you are experiencing any problems, please feel free to reach out to our Support Team - we’re available around the clock.
