Microsoft Outlook outage: what it means for Tandem users

Tandem is up and running as normal. Microsoft is having an outage that affects Outlook users, but that doesn’t change our service.

It may affect how you sign in. For some of you, when you log in to Tandem, we send a verification code by email. If your organisation’s email runs on Outlook, that code may arrive late or not at all until Microsoft fixes the problem.

If you’re already signed in, you can keep using Tandem as usual.

You can follow Microsoft’s progress on the Microsoft 365 Service health page. We’ll update this page when Outlook is working normally again.
