The Microsoft 365 outage that began on Thursday, November 12 is resolved, and all Ayin systems are fully working.
- CIM stayed up the whole time. Some CIM emails to outside recipients bounced while those recipients' own Microsoft 365 email was down. All of them were resent and delivered by about 10:15 AM PT today. - Ayin systems have been checked for impact, and any follow-up needed is done.
Microsoft reports no sign of malicious activity and will publish a report on the root cause in the coming days. If you're still missing a message or something isn't working, please contact Enterprise IT through IT Help in Teams or any of our usual support channels.
This is our final update on this issue. Thank you for your patience.

Update
Microsoft 365 outage: services are back to normal:
Microsoft reports that its systems are returning to normal, and Enterprise IT is seeing the same here. Outlook, Teams, SharePoint and the other Microsoft 365 apps should be working again.
- Delayed email: Email sent during the outage is still arriving, so some messages from yesterday will show older timestamps. This was a global outage that affected many other organizations too, so you may have received less email than usual yesterday. - CIM: We don't believe email sent from CIM was affected, because CIM doesn't use Microsoft to send email. We're still checking to make sure all Ayin systems have fully recovered.
We'll share more as we learn it, with Ayin staff and with our customers and partners. If something still isn't working for you, please contact IT Help in Teams or use any of our usual support channels.

Update
Update: Microsoft 365 is starting to recover
Microsoft has begun bringing its affected servers back online and is seeing some early recovery. Service will come back gradually, so some people may still have trouble with Outlook, Teams, SharePoint, Copilot, Planner, or To Do. Some Power BI users may be unable to export reports to PDF, and printing may fail for some people. When service returns, your apps may take a little while to reconnect. If something still isn't working, try closing and reopening it. Microsoft hasn't said when the recovery will be complete.
This is the last update from Enterprise IT until tomorrow morning. In the meantime, you can check Microsoft's status page for the latest: https://status.cloud.microsoft/

Update: Microsoft 365 outage is still ongoing
Microsoft hasn't fixed the problem yet. Their earlier fixes didn't work, and they're now testing a new approach on part of their systems before rolling it out more widely. Some people may still be unable to connect to Outlook, Teams, SharePoint, Copilot, Planner, or To Do. Some Power BI users may also be unable to export reports to PDF. Microsoft hasn't said when service will be back, so please plan for these tools to be unreliable for the rest of the day. You don't need to do anything. If a service isn't working, please wait and try again later. Microsoft's next update is due by 3:30 PM PT, and we'll keep you posted.
