    Key Properties and Their Practical Use

    • Exchange Online Sync Integration Mode (snwsdrsvsync.syncintegrationmode): Lets you set the synchronization mode between Exchange Online and Workplace Reservations to Strict, Personal Authentication, or Normal. Default is Normal.
    • Use User Default Time Zone (snwsdrsvsync.useuserdefaulttz): Controls whether reservations are synchronized according to the user's time zone or system time zone. Defaults to false, meaning system time zone is used if user time zone is not specified. Note that this does not affect reservations from Microsoft Exchange or Google Calendar.
    • Create Blocking Reservations (snwsdrsvsync.createblockingrsv): Enables creation of blocker reservations on workplace locations synchronized with calendar providers. Default is true.
    • Max Event Retry Count (snwsdrsvsync.maxeventretrycount): Defines how many times an event will be retried for processing. Default is 10 attempts.
    • Use Default Time Zone (snwsdrsvsync.usedefaulttz): Allows specifying a default time zone (such as “building”) during reservation synchronization.
    • Exchange Callback Time Limit (snwsdrsvsync.exchangecallbacktimelimit): Sets the maximum wait time (in negative seconds) to receive a callback notification from Microsoft Exchange. Default is -18000 seconds (5 hours). Since rejected or declined events do not trigger a notification, a scheduled job is provided to clean up such reservations.
    • Outlook Event Sync Interval (snwsdrsvsync.outlookeventsyncinterval): Internal property defining the sync interval (in minutes) for events from Microsoft Exchange. Must be set longer than the related scheduled job’s repeat interval. Default is 2 minutes.
    • Google Event Sync Interval (snwsdrsvsync.googleeventsyncinterval): Internal property controlling the interval (in minutes) for updating attendee details on reservations from Google Calendar. Should exceed the scheduled job’s interval. Default is 5 minutes.
    • Past Sync Period in Months (snwsdrsvsync.ewsPastSyncPeriodInMonths): Defines how many months back the synchronization should run for past reservations, with a recommendation to keep the sync result under 1000 reservations per sync. Default is 2 months.

    Practical Implications for ServiceNow Customers

    By configuring these properties, customers can optimize synchronization behavior between their calendar systems and Workplace Reservation Management, ensuring that reservation data is accurate, timely, and respects user time zones as needed. Understanding and adjusting retry counts, sync intervals, and time zone settings can improve performance and reliability of calendar integrations. Additionally, managing callback time limits and cleanup jobs helps maintain data integrity by handling rejected or declined reservations efficiently.
