Specifying notification communication methods

You can enable streaming or push notifications for Exchange Server 2013 and Exchange Server 2016 in NexJ Admin Console.
Before enabling the streaming communication method, you must specify the URL for the Exchange Server target in the ExternalEwsUrl property on Exchange Server 2013 or Exchange Server 2016.
To specify the notification communication method for an Exchange server:
  1. In NexJ Admin Console, navigate to the Synchronization page.
  2. In the Synchronization tab, select an exchange server in the Targets list.
  3. In the Exchange Server EWS zone, click the Edit button on the top right of the page.
    The Edit Exchange Server dialog opens.
  4. In the Version field, ensure that Exchange 2013 or Exchange 2016 is selected.
  5. In the Subscription Type field, select Streaming or Push.
  6. Click OK.
    The Edit Exchange Server dialog closes.

You have enabled streaming or push notifications for the selected Exchange server. If you enabled streaming notifications, note that subscriptions to user folders do not occur immediately. User folders become subscribed as follows:

  1. The Autodiscover service runs and obtains grouping information for links to user folders.
  2. Links to user folders subscribe on a periodic timer.
  3. Subscribed links are placed on a queue and wait to be streamed.
  4. Messages on the queue are processed and a streaming connection is opened for all links in that message.
You can view the subscription status of individual users folders in the Subscription State field in the Links list at the bottom of the Synchronization page.
