Microsoft 365: users may be unable to connect to multiple services

Incident Report for Copaco Cloud - Statuspage

Monitoring

Update from Microsoft:

We're seeing continued recovery progress across affected regions, with broader improvements now observed in North America and sustained improvements across much of Europe. We're also seeing encouraging recovery signals in Asia Pacific, although some users may continue to experience intermittent access issues or delayed email delivery as mitigation progresses across the remaining affected infrastructure.

Our focus remains on stabilizing recovered infrastructure, completing mitigation in the remaining impacted areas, and reducing delayed email queues and backlogs. We're closely monitoring service consistency and validating recovery across different connection methods as we work toward full mitigation.

At this time, we have no evidence of malicious activity associated with this incident. We will continue to treat this with urgency until full mitigation, and we will share a full Post-Incident Report with root cause and defense-in-depth actions after mitigation is complete.

Investigating

We are aware of an issue at Microsoft that affects Exchange Online and the Microsoft 365 services that depend on it. Microsoft is investigating the issue under incident reference MO1550821.

Impact
- Exchange Online: users may be unable to access their mailbox via Outlook on the web, Outlook desktop or mobile (ActiveSync), and email delivery may be delayed.
- Microsoft Teams: calls, meetings and chats work, but calendar functions (scheduling, invites, viewing meetings) may fail. Creating live events and private or shared channels may also fail.
- Microsoft 365 Copilot: Copilot Chat may not load, or may be unable to access email, calendar and files.
- Microsoft Defender for Office 365: Safe Links may fail to open rewritten URLs, and Quarantine may not load or release messages.
- Microsoft Purview: DLP, sensitivity labels, eDiscovery and audit searches may be affected, and protected content may not open.
- Microsoft Intune: device enrollment, check-in and compliance may be intermittently affected.
- Other services: Planner, To Do, Universal Print, Power Apps mobile sign-in, Microsoft Graph (mail, calendar and contacts data), the Microsoft 365 admin center and the Defender portal may also be affected.

Features that do not depend on Exchange Online keep working. For example, files stored in SharePoint Online and OneDrive can still be opened.

We are monitoring the issue and will post an update as soon as Microsoft shares more information. Admins can find the full details in the Microsoft 365 admin center under Service health, reference MO1550821.
