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.
