Service Advisory: Microsoft 365 Email Outage Impacting Microsoft Customers Globally

Written by ALIANDO | Jan 22, 2026 11:38:33 PM

We want to inform our customers of a current service disruption affecting email services hosted on Microsoft 365.

Microsoft is currently experiencing a service outage impacting email functionality in the North America region. This issue originates within Microsoft’s infrastructure and is affecting the ability to send and receive emails across Microsoft 365.

How This Affects ALIANDO Customers

Due to this Microsoft outage:

  • ALIANDO employees are currently unable to send or receive emails
  • Email-based communication with ALIANDO may be delayed or unavailable
  • Other Microsoft 365 services may continue to function normally

Please note that this is not an ALIANDO system failure, but rather an external service interruption within Microsoft’s cloud environment.

What Is Being Done

Microsoft has confirmed the issue and is actively working to restore full email functionality as quickly as possible. Their engineering teams have identified the problem area within their infrastructure and are implementing remediation steps.

ALIANDO is closely monitoring Microsoft’s official service updates and will provide timely information as the situation evolves.

Recommended Alternative Communication Channels

While email services remain unavailable, we recommend contacting us through:

  • Microsoft Teams
  • Your usual non‑email communication channels
  • Existing escalation or support pathways, if urgent assistance is required

These alternatives will help ensure uninterrupted collaboration and support during the outage.

Our Commitment to Transparency

We understand how disruptive communication outages can be and sincerely appreciate your patience during this time. ALIANDO is committed to keeping our customers informed and will share updates as soon as additional information becomes available.

Thank you for your understanding as Microsoft works toward a full resolution.

The ALIANDO Team
