Microsoft is dealing with a significant service disruption that's causing authentication problems and delays or failures in email delivery for Exchange Online users.

The company first recognized this situation at 5:30 PM UTC, as it started to investigate a surge of reports from users on social media.

According to the outage monitoring service Downdetector, tens of thousands of Exchange Online users are impacted, facing challenges in receiving emails through Outlook and accessing the Exchange Online platform.
