Microsoft Says Patch Begins Improving Stability as Microsoft 365 Disruption Continues

Microsoft said a patch to a component that handles authentication and routing was beginning to improve stability in part of its infrastructure as the Microsoft 365 disruption continued.

The update came at about 2:24 a.m. ET (07:24 UTC) Friday. Microsoft said it was expanding the patch after seeing early gains, but did not announce a full recovery.

Outlook and some Teams features that depend on Exchange Online remained affected. Most core Teams functions, including calls, meetings, group chats and channel messages, were not affected.
