Websocket connections to critical Microsoft 365 domains
We continue to get warnings on our tenant regarding Websocket connectivity errors. Full message states: We've detected WebSocket Secure (WSS) failures to the following unified domains. I can't publish the wildcarded URLs here, but you'll know the ones I mean from your M365 admin networking connectivity insights page. I don't understand this as we effectively have those domains whitelisted/bypassing https inspection etc and everything seems to be working as normal. Nothing has been changed as far I'm aware. Anyone else seen this warning in their tenancy? Anything else we can check or try to sort the issue. Or is it just something to note?? We have a support ticket in - but on doing the initial check nothing is showing up. Our networking team have confirmed with me that the connection sends data to Microsoft uninspected. For that reason, it shouldn’t cause the websocket errors that are being reported.Optimizing Customer Network Connectivity for #Microsoft 365 Copilot
Network connectivity page in M365 admin center is the go-to place for tenant, network security administrators to review health and readiness of customer network connectivity setup essential for M365 applications. Problem statement Customers blocking WebSocket connections in their network infrastructure leads to broken experience for M365 Copilot users. Copilot uses WebSocket and tenant admins have no visibility into the failed WebSocket connections for their users, rendering the customer network setup not ready for Copilot roll out. Users with WebSocket connection failure will have a broken Copilot experience, here is a glimpse. We are pleased to announce the following new features in M365 admin center that are available to all customers. Admins can now view Service health notifications in Microsoft 365 admin center for Network insights detected for their tenant. They may also receive an email if opted-in to receive email notifications. The service health notification has a deep link that takes them directly to the detected network insight for their tenant, they will receive one notification per insight detected. Detected network insights include failed network connections for M365 Copilot, this public article documents the three network insights we detect Microsoft 365 Network Insights - Microsoft 365 Enterprise | Microsoft Learn Failed HTTPS connections for Unified domains *.cloud.microsoft, *.static.microsoft, *.usercontent.microsoft Failed WebSocket connections for *.cloud.microsoft Network Intermediation (TLS break and inspect) impacting performance I received a Service health notification for WebSocket or HTTPS connection failures, what should I do? Within the Service health notification there is a hyperlink that directly takes you to the Insights page in Network Connectivity. You can also go to the Insights page and click on the network insight, this shows the locations for which the insight has been detected, click on any location to review the location specific details and summary, the location summary provides you information like egress IP addresses (your source IPs from where we see connection failures) for this location. More information available in this video. 1. Visibility into failed network connections for M365 Copilot Tenant admins can now see in Microsoft 365 admin center (Microsoft 365 network connectivity - Microsoft 365 admin center) when their network impacts user connections to M365 apps, including WebSocket connections for M365 Copilot. The new report shows failure rate percentage, also known as the error rate percentage, for failed HTTPS and WebSocket connections to customer facing M365 Unified domains such as *.cloud.microsoft, *.static.microsoft, and *.usercontent.microsoft. A high error rate in this report indicates blocked network connections that impacts connectivity for various M365 applications and calls for immediate action from the tenant admin to allow blocked connections. 2. Visibility into user network latency for M365 Copilot Tenant admins can now view the network assessment points for Microsoft 365 Copilot, the assessment points are based on the network latency experienced by Copilot users. The lower the network latency, the higher the network assessment points for Microsoft 365 Copilot, providing a clear picture for tenant admins about the high network latency experienced by their users for M365 Copilot. In addition to the above, we recently announced M365 network connectivity test tool for individual users to test and validate if they successfully meet the network connectivity requirements for M365 Copilot.

Hi all, Cards on the table—I’m a Product Manager for a solution focused on Microsoft 365 management as well as driving optimisation into innovation. My background is sysadmin-heavy, which led me to building the solution before moving into product. I’m not here to pitch anything but genuinely keen to hear from the community: What are your biggest pain points in managing M365, Azure, Copilot? What challenges do you face with user optimisation, processes etc? Are you using any tools today to help, or is it mostly manual? What is one thing that would make your life so much easier? Would love to hear what’s working (or not working) for you, as it would help me massively! Thanks!Announcing Microsoft 365 network connectivity test for Microsoft 365 Copilot public preview
