These properties are located in theSystem Properties \[sysproperties\]table, accessible viasysproperties.list. Show full answer Show less ## Key Properties and Their Practical Use * **snwsdrsvsync.syncintegrationmode**: Defines the synchronization mode between Exchange Online and Workplace Reservation Management. Modes include Strict, Personal Authentication, or Normal (default). This controls how reservations are synced. * **snwsdrsvsync.useuserdefaulttz**: Enables synchronization of reservations according to the user's time zone if set to true; otherwise, system time zone or UTC is used. This does not affect reservations from Microsoft Exchange or Google Calendar. * **snwsdrsvsync.createblockingrsv**: When true, creates blocker reservations on workplace locations during synchronization to prevent double bookings. * **snwsdrsvsync.maxeventretrycount**: Sets the number of retry attempts for processing a reservation event, defaulting to 10 retries. * **snwsdrsvsync.usedefaulttz**: Specifies which default time zone to use during synchronization, typically set to the building's time zone. * **snwsdrsvsync.exchangecallbacktimelimit**: Defines the maximum wait time (in negative seconds, default -18000 or 5 hours) for Microsoft Exchange callbacks during synchronization. Note that events declined or rejected by Outlook are not notified; a cleanup job is recommended to remove such reservations. * **snwsdrsvsync.outlookeventsyncinterval**: Controls the interval in minutes for syncing events from Microsoft Exchange to Workplace Reservations. This should be greater than the repeat interval of the corresponding scheduled job (default 2 minutes). * **snwsdrsvsync.googleeventsyncinterval**: Controls the interval for updating attendee details from Google Calendar reservations, requiring a value greater than the scheduled job repeat interval (default 5 minutes). * **snwsdrsvsync.ewsPastSyncPeriodInMonths**: Specifies how many months back the synchronization will run for past reservations. It is important to keep the number of reservations per sync under 1000 to maintain performance (default 2 months). ## Practical Implications for ServiceNow Customers By configuring these properties, customers can tailor workplace reservation synchronization to their organizational needs, including time zone handling, synchronization frequency, retry logic, and managing reservation blocking. Proper configuration helps ensure accurate, timely reservation data between Workplace Reservation Management and calendar providers like Microsoft Exchange and Google Calendar, reducing double bookings and improving user experience. Additionally, understanding and managing synchronization intervals and callback time limits helps maintain system performance and data consistency. Scheduled cleanup jobs complement these properties by handling rejected or declined events automatically. Customize the properties available with Workplace Calendar Synchronization.

Either the system's time zone or the user's time zone is used to update and synchronize reservation. First, the property checks if the user has a time zone specified or not. If the user has not specified any time zone, the system's time zone is used. Again, if the system has no time zone specified, then the property uses the UTC time zone. Reservations synchronized from Microsoft Exchange and Google Calendar to Workplace Service Delivery are not affected. * Type: true/false * Default value: false {#properties-installed-with-workplace-calendar-syncn__ul_e5n_xkh_rpb} | | sn_wsd_rsvsync.create_blocking_rsv | This property enables you to create blocker reservations on workplace locations that are synchronized with the calendar provider. * Type: true/false * Default type: true {#properties-installed-with-workplace-calendar-syncn__ul_jjd_dlh_rpb} | | sn_wsd_rsvsync.max_event_retry_count | This property enables you to specify after how many times an event must be reprocessed. * Type: Integer * Default value: 10 {#properties-installed-with-workplace-calendar-syncn__ul_nty_klh_rpb} | | sn_wsd_rsvsync.use_default_tz | This property enables you to use the default time zones during the reservation synchronization. * Type: String * Default type: building {#properties-installed-with-workplace-calendar-syncn__ul_uxt_5ks_fsb} | | sn_wsd_rsvsync.exchange_callback_time_limit | This property enables you to specify the maximum time limit to wait for Microsoft exchange to notify with a callback. Specify the time limit in negative seconds as specified in the default value. Note: You won't be notified when an event is rejected or declined by Microsoft Outlook. For the same reason, a scheduled job - Clean-up Awaiting/Rejected Reservations, is available that you can run on any suitable frequency to clear the reservations rejected or declined by the Microsoft Outlook calendar. * Type: Integer * Default value: -18000 (5 hours) {#properties-installed-with-workplace-calendar-syncn__ul_tb3_vn3_dxb} | | sn_wsd_rsvsync.outlook_event_sync_interval | This property is used internally by the application, it enables you to set the time(in minutes) to synchronize events received by Microsoft Exchange with Workplace Reservation Management application.
