Microsoft 365 network connectivity test hanging on Running web browser tests
Hi community, I have this issue on different devices and from different locations. Whenever I visit https://connectivity.m365.cloud.microsoft/ and want to run the test, I select "Add location" instead of "Automatically detect location", because I'm on a laptop without GPS and don't wont to use the WiFi recognition. I start typing the town, select it from the list of choices, and click on "Run test". Nevertheless, a pop-up comes asking for access to location services, to which I select "Block" After that, the web application gets stuck on "Running web browser tests" and is not showing any results. I had this issue on Windows 10 and on Windows 11, and on Chrome and on Edge. Any idea how to solve this?BoSoloJul 24, 2025Copper Contributor167Views0likes5CommentsReleased the full version of M365 connectivity test tool (MCT) in GCC environment

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.ML79Jun 17, 2025Copper Contributor593Views0likes3CommentsOptimizing 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, We are troubleshooting a voice packet loss issue in Tokyo and we've been able to force our outbound traffic to use a particular provider above IX peering and another provider. How do i see what route the return traffic (from Microsoft) is taking as there could be a few different routes? thanks,jonasb120Apr 03, 2025Copper Contributor167Views0likes1CommentMicrosoft 365 network connectivity test for Microsoft 365 Copilot Generally Available
I am thrilled to announce that the Microsoft 365 network connectivity test for Microsoft 365 Copilot is now generally available worldwide. Now all the customers can run the most comprehensive connectivity test of the history from https://connectivity.m365.cloud.microsoft . ✌️😁❤️ This release also includes two improvements from the user experience perspective: Enhancing the sign-in experience for smoother user interactions (like SSO) and providing more user-friendly guidance for saving report data. As a result, we can also measure tenant information with sign-in users, giving us better insights into the business impact of the tool. We also fixed a bug in the rich client that previously blocked the test process due to firewall warnings, increasing the completion rate and performance of the tests.Ares ChenMar 25, 2025Microsoft132Views0likes0CommentsHello Azure Networking

Hi there, We have been trying to install MS365 apps for some time, but so far only partially successful... Office 2019 was installed on the laptops via XML, we first tried it in Intune with the app ‘Install MS365 Apps’, but without success. We then created our own .xml, the installation XML contains a line that deletes Office 2019 and then installs MS365, we installed this programme as a WIN32 app. It has worked on 4 computers, on all others there are fatal errors, e.g. : (0x80070643) and 0x8007426E, otherwise the programme is pending installation. Here is the new installation xml script: <Configuration ID=""> <Display Level="None" AcceptEULA="True"/> <Property Name="FORCEAPPSHUTDOWN" Value="True"/> <Remove> <Product ID="Standard2019Volume"/> </Remove> <Info Description=""/> <Add OfficeClientEdition="64" Channel="Current" MigrateArch="TRUE"> <Product ID="O365BusinessRetail"> <Language ID="de-de"/> <ExcludeApp ID="Groove"/> <ExcludeApp ID="Lync"/> </Product> <Product ID="VisioStd2019Volume" PIDKEY=""> <Language ID="de-de"/> <ExcludeApp ID="Groove"/> <ExcludeApp ID="Lync"/> </Product> </Add> <Property Name="SharedComputerLicensing" Value="0"/> <Property Name="FORCEAPPSHUTDOWN" Value="FALSE"/> <Property Name="DeviceBasedLicensing" Value="0"/> <Property Name="SCLCacheOverride" Value="0"/> <Property Name="AUTOACTIVATE" Value="1"/> <Updates Enabled="TRUE"/> <RemoveMSI/> <AppSettings> <Setup Name="Company" Value=""/> <User Key="software\microsoft\office\16.0\excel\options" Name="defaultformat" Value="51" Type="REG_DWORD" App="excel16" Id="L_SaveExcelfilesas"/> <User Key="software\microsoft\office\16.0\powerpoint\options" Name="defaultformat" Value="27" Type="REG_DWORD" App="ppt16" Id="L_SavePowerPointfilesas"/> <User Key="software\microsoft\office\16.0\word\options" Name="defaultformat" Value="" Type="REG_SZ" App="word16" Id="L_SaveWordfilesas"/> </AppSettings> <Display Level="Full" AcceptEULA="TRUE"/> </Configuration> The question now is how we can get Office 2019 uninstalled and MS365 installed in one go without the users noticing anything. After 2 weeks and a lot of testing, we are very desperate ... Lg ChrisF_C_KMar 13, 2025Copper Contributor920Views0likes1CommentM365 Management
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!JamesMM_PrismFeb 07, 2025Copper Contributor118Views0likes1Comment
