Microsoft 365 Outage: Current Service Status and How to Maintain Email Access

12 November 2026 | Service disruption update

Microsoft is currently investigating a widespread service disruption affecting Microsoft 365, with users across multiple regions reporting difficulties accessing Outlook, Exchange Online and other Microsoft cloud services.

Bedroq is monitoring the situation and advising affected customers on how they can maintain access to essential email communications through Mimecast.

What is the current Microsoft 365 service status?

As of the evening of 12 November 2026, Microsoft is continuing to investigate and address connectivity issues affecting its cloud infrastructure.

The disruption was initially reported in the Americas but Microsoft has since confirmed that users in any region may be affected, including the UK.

The primary issue involves Exchange Online, Microsoft’s cloud-based email platform. However, connectivity problems have also been reported across several other Microsoft 365 services.

Services potentially affected include:

  • Exchange Online and Outlook: Users may experience difficulties accessing mailboxes, sending or receiving emails, or connecting through desktop, web and mobile applications.
  • Microsoft Teams: Some users have reported connectivity and messaging issues.
  • SharePoint Online: Users may experience problems accessing cloud-hosted documents and collaboration services.
  • Microsoft 365 Copilot: Some users have experienced service availability issues.
  • Microsoft Defender XDR: Connectivity to security management services may also be affected.

The impact varies between users and organisations, and not all customers will experience the same symptoms.

Microsoft is tracking the disruption under service health incident references EX1550543 (Exchange Online) and MO1550821 (wider Microsoft 365 connectivity).

How Bedroq customers can continue accessing their emails

For affected Bedroq customers using Mimecast with email continuity services enabled, an alternative method of accessing email may be available while Microsoft works to restore normal service.

If you are unable to access Outlook, you can use the Mimecast Personal Portal to access your available emails.

To do this:

  1. Open your organisation’s Mimecast Personal Portal.
  2. Sign in using your usual credentials and authentication method.
  3. Access your available messages and, where continuity functionality is enabled, continue sending and receiving emails.

The availability of these features depends on your organisation’s Mimecast configuration and the nature of the disruption.

If you are unsure how to access Mimecast or encounter any difficulties, please contact the Bedroq Service Desk through your usual support channels.

Bedroq continues to monitor Microsoft’s service health updates and will support customers experiencing disruption.

Customers requiring assistance should contact the Bedroq Service Desk through their normal support channels.
