This incident has been resolved. Microsoft has deployed a fix for the underlying issue (Microsoft issue ID: MO1331639), and sync operations from Microsoft To-Dos into Ninety are now functioning normally. Two-way sync has been fully restored.
Thank you for your patience while Microsoft worked through the issue on their end.

Identified
We are aware of an issue affecting the Microsoft To-Do integration. All sync operations from Microsoft To-Dos into Ninety are currently failing (Ninety to Microsoft remains operational), the integration will not regain full functionality until Microsoft resolves an issue on their service (Microsoft issue ID: MO1331639).
This issue originates within Microsoft’s platform and is outside of Ninety’s control. No action is required on your part; sync will resume automatically once Microsoft deploys a fix.
We are monitoring Microsoft’s progress and will update this page as new information becomes available.
