Dear Customer,
We would like to proactively bring to your attention a global service disruption affecting Microsoft 365 services, reported on November 12, 2026. Microsoft is currently facing an outage that is affecting Outlook. Because of this, email notifications for support tickets may be delayed or may not be reached to either you or our support team right now.
Please note, your tickets are safe and our team is working on them as usual. You just may not get an email when there is an update.
Potential impact
Depending on your usage of Microsoft services, you may experience:
- Outlook / Exchange Online: Difficulty accessing emails, sending or receiving emails, and possible delays in email delivery.
- Microsoft Teams: Intermittent issues with calendar access, meeting scheduling and certain functionalities. Core messaging and online meetings have been reported as relatively less affected.
- SharePoint / OneDrive: Potential issues with features dependent on Exchange Online, although direct file access may remain functional.
- Other Microsoft 365 services: Certain functionalities in Copilot, Planner, To Do and other dependent services may also be impacted.
What we request you to do:
- Please log in to the support portal and check your ticket status directly, instead of waiting for an email.
- For any urgent or high-priority issue, please directly call your Caliber SPOC or the team supporting you.
- If you reply to a ticket by email, please also add the same comment on the portal so we don’t miss it.
- Add an alternate email ID (non-Outlook) in your portal profile if you have one.
If you experience any disruption to business-critical activities or integrations, please call your respective Caliber SPOC so that we can assess the impact and coordinate the necessary support.
We appreciate your understanding and patience as Microsoft works towards restoring normal service operations. We will update this notice as soon as the issue is resolved. Thank you for your patience and support.
