Introducing The Event Subscription Hub
Since its inception, OnTime for Microsoft has relied on the EWS API to subscribe to streaming notifications for changed events. However, the popularity of EWS streaming notifications has gradually declined, and we are encountering an increasing number of issues with this method.
The Graph API does not support the streaming notification method, prompting us to completely rethink how OnTime receives notifications as EWS support for MS 365 is scheduled to be deprecated.
Microsoft Graph API provides a modern notification mechanism that has several advantages over EWS Streaming Subscriptions:
– Doesn’t requires a persistent connection for each subscription
– Can handle many subscriptions efficiently with retry policies and batching.
– Supports subscription expiration and renewal, typically up to 60 minutes for high-security scenarios.
Subscription Hub is an HTTP-based callback API that receives change notifications from Microsoft Graph, handles subscriptions life-cycle and prepares needed data for OnTime Server.
While the EWS Streaming subscription method is still supported we encourage our user organisations to start switching to the OnTime Subscription Hub.

Desktop
- Repeat Events: An error was triggered when creating a repeating event longer than 24 hours. Events are now limited to 24 hours if repetition is enabled.
