    Procedure

    1. Navigate to All > Workplace Calendar Synchronization > Configurations > Calendar Providers.
    2. Select New.
    3. Fill in the form fields.
      Table 1. Calendar Providers form
      Field Description
      Name Enter the name of the provider. For example: On Premises
      Description Enter a short description.
      Active Option to activate the On-premises calendar provider.
      Provider Configuration
      Calendar processor Calendar processor for the synchronization. Select Microsoft EWS as the processor.
      Override alias? Option to enable selection of your own connection and credential alias. If the option is not enabled, then the default connection and credential alias is used.
      Connection & credential alias Select the connection and credential alias that you created on your own for the calendar provider. This option appears only if you have selected the Override alias? option. If an alias is not specified, then the default connection and credential alias is used.
      Page size Page size of the calendar items. You can set the page size from 1 to 500.
      Sync batch size Size of batches during a synchronization. This field is automatically set to 500, which means a sync batch handles 500 items at a time. If there are more than 500 items, the rest is displayed in the next sync batch.
      Sync batch interval Time interval between sync batches. This field is automatically set to 60 seconds.
      Synchronize attendees Enable this option to synchronize attendees as well while synchronizing reservations.
      Sync start date time The start date and time of the synchronization. The sync generates information from this date.
      Important:
      The past sync duration must not exceed 1825 days.
      Sync end date time End date and time of the synchronization. The sync generates information until this date. The recommended setting is at least 5 years from the Sync start date time.
      Important:
      The past sync duration must not exceed 1825 days.
      Strict mode Select the option to enable strict mode.

      If you enable this option, events are not directly created in the employee's calendar, instead, they are sent to a general email address. Employees are invited to the event. They can only make changes using the Workplace Reservation Management application.
      Strict mode email Strict mode email address used to create reservations and to receive reservation-related notifications. Employees are considered as invitees in the reservation.
      Sync past reservations Select the option to synchronize all the past reservations from the specified Sync start date time to Sync end date time.
      Note:
      Ensure that the reservations that you want to sync from the past are not above 1000 per room. If in cases the expected number of past events are more than 1000, it is recommended to modify the system property sn_wsd_rsvsync.ewsPastSyncPeriodInMonths. Specify the value in months keeping in mind the expected past reservations. A single sync syncs reservations from those many months. Ensure that the specified number of months do not have more than 1000 reservations.
    4. Select Submit.
      The On-premises calendar provider is created.
    5. In the Reservable Sync Configurations related list, add the reservable sync configurations with which you want to synchronize reservations.
      To add a new one, refer to Add a Reservable Sync Configuration.

    What to do next

    • Set the scheduled job, WSDRS Sync Calendar items to True. The scheduled job is set to False by default and it must be enabled to start synchronizing. You can set the scheduled job time as you want. At any time, you can also manually execute it.
