ONTIME BACKEND

• This release addresses an issue reported on Tuesday, October 29, 2024. We received multiple support requests from customers experiencing synchronization issues affecting some or all users. Our investigation traced the problem to a change in Microsoft’s Exchange Web Services (EWS) API, which no longer returns the expected “IsCancelled” parameter for events. The issue in the OnTime log will show up as "This property was requested, but it wasn't returned by the server".
  In version 6.1.8b, we’ve implemented a workaround that assumes the “IsCancelled” value is false if not received from the EWS API. This adjustment is relevant for organizations using the OnTime API, but it does not affect the general OnTime desktop UI.
• Additionally, due to heavy throttling of the EWS API in the directory sync process with version 6.1.8a—particularly in Japan—we’ve reduced the maximum number of threads from 10 to 2. In a future update, this number will be dynamically adjustable to mitigate throttling, and the maximum number of threads will be configurable.
