Faults have also been reported on email service Microsoft Outlook, as well as a number of other products owned by Microsoft.
In an update posted on Twitter, Microsoft said: “We’re investigating issues impacting multiple Microsoft 365 services. More info can be found in the admin center under MO502273.”
Microsoft later added: “We’ve identified a potential networking issue and are reviewing telemetry to determine the next troubleshooting steps.”
