Update: Microsoft 365 outage resolved, multi-factor authentication codes now arriving as normal
Updated: 13/11/2026 18:25
Summary
Microsoft has confirmed that the global Microsoft 365 outage that started on the afternoon of Thursday 12 November is now resolved. Emails containing sign-in codes and password reset links should now arrive as normal.
Ciphr’s own systems were not affected by the outage, and your accounts, passwords and data stayed secure throughout.
What happened
From the afternoon of Thursday 12 November until Friday 13 November at 17:57, a Microsoft outage affected Outlook and Exchange Online around the world. Because of this, some users who receive their Ciphr sign-in codes or password reset links by email had delays, or did not receive them at all.
What you need to do now
Most users won’t need to do anything. If you had trouble signing in during the outage:
- Request a new code. Any sign-in codes sent during the outage will probably have expired, so ask for a new one rather than using an old email.
- Request a new password reset link. Reset links sent during the outage may have expired too. If yours doesn’t work, start the reset again.
-
Check your junk or spam folder. Delayed emails may arrive in a batch over the next few hours, and some could end up in junk.
If your code or reset email still hasn’t arrived after 30 minutes, please raise a Zendesk ticket and our support team will help during your support working hours.
Set up an authenticator app for future sign-ins
An authenticator app is not affected by email outages, and we recommend all users set one up. This may require your HR system administrator to enable it.
We will update this article when Microsoft confirms the outage is resolved. If you need to communicate with us, please raise a Zendesk ticket rather than sending an email.
