Exchange cached and non-cached mode

The ScheduleOnce integration with Outlook works regardless of whether you are using Exchange in cached mode or non-cache mode. The Cached Exchange Mode is the default mode in Outlook and is the recommended option to optimize the performance with the ScheduleOnce connector.

The performance of the connector will be affected depending on the mode that you have enabled in Outlook:

  • When using the Cached Exchange Mode, a copy of your Exchange Calendar is stored on your computer. This copy provides quick access to your data and is frequently synced with the Exchange server.  The cached mode is less memory and CPU intensive on both the client-side and the server-side than the non-cached mode, improving the performance of Outlook and the ScheduleOnce connector.

  • If you are using Exchange and working in non-cached mode, Outlook is retrieving data from the server on any connector sync. This means that Outlook and the connection to ScheduleOnce will respond slower than in the Cached mode.

If you are experiencing slow performance in your connection to ScheduleOnce, the first thing to check is that Cached Exchange mode is enabled. Learn more about turning on Cached Exchange Mode
