Microsoft has acknowledged the incident and is working to restore services following reports of connectivity issues affecting its underlying infrastructure.

Which Microsoft services are affected?

The disruption is affecting several Microsoft 365 services, including:

Exchange Online & Outlook: Users may be unable to access their mailboxes, send or receive emails, with some messages experiencing delivery delays.

Microsoft Teams: Users may experience issues with certain features, including calendar access, meeting scheduling and other integrations.

Microsoft Copilot: Some users may be unable to access Copilot Chat or receive responses.

SharePoint Online: Certain features and integrations may be affected.

Other Microsoft 365 applications: Additional services, including Planner, To Do and some Microsoft security and administration tools, may also experience intermittent issues.

The impact may vary between organisations and individual users, depending on which services and features they rely on.

What is causing the disruption?

Microsoft has identified issues affecting the availability and performance of its underlying infrastructure across multiple regions.

The company has been investigating server availability and connectivity problems, implementing measures to restore capacity and gradually bring affected services back online.

Recovery efforts are ongoing, although Microsoft has indicated that some of its initial fixes have not worked as expected. As a result, users may continue to experience intermittent disruption while further work is carried out.

There is currently no confirmed timeframe for the full restoration of all affected services.

What should businesses do?

During a widespread service disruption, it is important to remain patient and avoid making unnecessary changes to your IT systems while Microsoft works towards a resolution.

We recommend that businesses:

Monitor Microsoft’s updates: Keep up to date with the latest information through Microsoft’s official service status page.

Use alternative communication methods: Where possible, consider telephone communication if email or Teams functionality is unavailable.

Report any additional IT issues: Continue to report problems to your IT support provider so that any unrelated issues can be investigated.

Be mindful of delayed emails: Check for outstanding communications once services begin returning to normal.
