Latest Message<\/th>\nTitle: Users may experience issues when utilizing multiple Microsoft 365 services<\/p>\n

User impact: Users may experience issues when utilizing multiple Microsoft 365 services.<\/p>\n

More info: Impact includes, but may not be limited to, the below services and scenarios. We will update this list as our understanding of the issue progresses.<\/p>\n

OneDrive for Business and SharePoint Online:
-Users may be unable to load or refresh portions of OneDrive and SharePoint, including account and storage information, search results, Favorites, Followed and Shared With Me content, recent files, lists, and news.
Some users may also experience delayed or failed file opening, Office policy-label retrieval, OneDrive synchronization, mobile camera upload, and video playback.
Users may see partial page failures, missing or stale content, repeated retries, and operation timeouts rather than a complete platform outage. <\/p>\n

Exchange Online:
-Users may be unable to connect to, or experience degraded functionality, with Exchange Online. All connection methods are affected.<\/p>\n

Microsoft Teams:
-Users may experience issues with calendar functionality and search. Users\u2019 presence may be stale and not update automatically or through manual adjustment. User location adjustment may fail.<\/p>\n

Microsoft Purview:
-Users may face intermittent authorization failures across solutions in Purview. Purview admins can\u2019t access the portal.
Additionally, in Microsoft Purview Communication Compliance, users may see errors when loading Communication Compliance policies and Data Loss Prevention (DLP) policies. Communication Compliance policy creation and evaluation may be delayed.<\/p>\n

Microsoft Defender XDR:
-Users may experience intermittent authorization failures across solutions in Defender.<\/p>\n

Current status: We’re continuing to perform comprehensive tests to ensure our mitigation strategy effectively resolves the issue without introducing additional impact. In parallel, we’re exploring alternative remediation avenues to minimize impact in the interim. <\/p>\n

Scope of impact: Users attempting to perform any of the outlined impact scenarios may be affected by this event.<\/p>\n

Start Time: Monday, August 31, 2026, at 3:08 PM UTC<\/p>\n

Preliminary root cause: An issue within a core authentication configuration used by multiple Microsoft 365 services is resulting in impact.<\/p>\n

Next update by: Monday, August 31, 2026, at 8:30 PM UTC<\/td>\n<\/tr>\n
