Microsoft is currently addressing a significant issue that has hindered users from installing the Microsoft 365 desktop applications on Windows devices. According to a service alert released on Friday, the problem stems from misconfigured authentication components, impacting customers attempting to install specific versions of the software.
Details of the Issue
The affected versions include Microsoft 365 desktop apps version 2508 (Build 19127.20358) and version 2507 (Build 19029.20294). In their update, Microsoft acknowledged the misconfiguration and stated that they are actively working to reconfigure the authentication components. A resolution is expected to be deployed later today.
“A newly released set of authentication components contain a misconfiguration that prevents users from installing Microsoft 365 desktop apps on Windows devices,” Microsoft noted in their update. They are developing two builds to rectify the misconfigurations, with the build for version 2508 already validated and in the deployment phase. The second build for version 2507 is anticipated to be ready for final validation in the next scheduled update.
Scope of Impact
While Microsoft has not disclosed the exact number of affected customers or the specific regions impacted, the issue has been classified as incident OP1186186, which typically indicates a critical service disruption with noticeable user impact.
In addition to this issue, Microsoft is also tackling another problem, tracked as MO1176905, which affects a limited number of admins and users by restricting access to various Microsoft 365 services. This particular issue arises for customers who have the Microsoft 365 Group SecurityEnabled set to false, a change that was made as the default value following a recent misconfiguration.
Recent Resolutions
Last week, Microsoft successfully resolved a bug related to Microsoft Intune (IT1185063) that had prevented some users from enrolling new AOSP (Android Open Source Project) or Android Personal Work Profile devices. Additionally, in October, the company mitigated a DNS outage that affected customers globally, disrupting their ability to log into company networks and access Microsoft 365 and Microsoft Azure services.
As the situation develops, Microsoft remains committed to restoring full functionality for its users and ensuring a seamless experience across its platforms.
