Introduction to Ivanti Email+ Notification Services

When a mail is received on an iOS mobile device, a notification appears if real-time notification is enabled. For each mail there are two notifications received:

  • Apple APNS notification: Shows up immediately on the lock screen (depending on the Email+ Notification settings in your device Settings). This notification has the text: “You have new messages”.
  • Email+ notification: The Email+app fetches the email summary for the new unread email, removes the original device notification, and replaces it with a new notification. The second notification shows either the unread email count or summary of the new emails, depending on your Email+ settings.

VoIP notifications for Email+ are not supported starting Email+ 3.13.0 and later, due to the changes in Apple Policy with regards to notifications. This impacts the VIP notifications outside of work hours, other notifications such as Work hours notifications and the Weekend notifications work as before.

Email+ Notification Services (ENS) is the recommended solution to fix this issue.

There are two different notification deliverable mechanism for real-time notification:

  1. Cloud based service which only supports work hour notification, see About real-time push notifications for Email+ for iOS section.
  2. ENS based service which supports VIP email only notifications. The following sections describes about ENS and how to configure it on your device.

About Ivanti Email+ Notification Services

Email+ Notification Service leverages a standalone server that is based on existing Sentry and hosted inside the organizations firewall. This server is configurable on UEM servers and leverages a service account on Microsoft Exchange to retrieve email metadata information (such as Sender, Subject, and Body Snippet) required to support VIP mails notifications outside of office hours and direct detail notifications.

The following diagram describes how the ENS solution works:

Figure 1. Email+ Notification Services Architecture

  1. Email+ App: The Email+ app registers callback URL with Microsoft Exchange server to send out work hours, list of VIP contacts, key-value pairs settings, and VIP notifications outside work hours.
  2. Microsoft Exchange: When a new mail is received in the folder that you are subscribed to, Microsoft Exchange sends a notification to Email+ Notification Proxy (ENP) which consists of Message Id and Folder Id for the new received mail.
  3. Email+ Notification Proxy: ENP logs in to the exchange server using a service account and pulls the following information about the mail: Senders email address
    1. Subject line
    2. Snippet of the mail
    3. ENP applies and verifies the rules. Once the verifications is complete, it creates a payload and sends it to real-time push notification server on the Ivanti Neurons for MDM.
  4. Real-time push notifications: The MobileIron CNS relays the information to Apple Push Notification service (APNs).
  5. Apple Push Notification service (APNs): Notifies the iOS device.
  6. Notification workflow on Email+: This feature requires users to be subscribed to CNS for Real Time Notifications. iOS displays a notification to the user indicating that there are new messages.
  7. Mailbox active sync: A notification is triggered to Email+, to open the correct mailbox a sync up is performed to co-relate the notification and the mail.

Enable Email+ settings on your device to receive notifications. In Email+ app, go to Settings > Notifications and enable Work Hours Only option first to enable Weekend Alerts or VIP Allowed After Work Hours option. The VIP related options are not be enabled if ENS is not configured, as there is no service account to check if the sender is a VIP contact (ensure that the contacts are marked as VIP).

When notification settings is changed, a note similar to the following is displayed:

Changes to alert times will come into effect after 'X' hours. The default interval is 1440 minutes.

If you are using CNS only for real-time notifications. all the settings related to VIP are not visible on the Email+ app and cannot process notifications outside work hours other than delivering notifications over weekend.

The following section describes how to configure ENS.

Limitation: The ENS solution is not supported on Microsoft Exchange Office 365.

Before you begin 

  • Supported on Ivanti EPMM or later, Ivanti Neurons for MDM R70 and later, and Sentry 9.8.5.
  • Ensure that you have configured a service account on Microsoft Exchange Server (Service account on exchange impersonates other mailboxes when accessing exchange over various supported protocols. For the purpose of Exchange Notification Proxy (ENP), Microsoft’s Exchange Web Services (EWS) protocol is used to access mailbox messages.)
  • Ensure that you have the JWT token of CNS production server. For more information, see About real-time push notifications for Email+ for iOS section.

The term JWT token is also referred as Authorization Token, Token, and notification_server_authorization in Ivanti products.

  • Standalone Sentry must be configured ActiveSync with a publicly trusted certificate.
  • Ensure that the Exchange servers are configured with the service account. The servers must have identity certificate to authenticate the service account
  • If Exchange server version support is earlier than TLS v1.2, then the supported protocols should be configured in Incoming protocols on MICS.

Configuring service account

Service account on Microsoft Exchange impersonates other mailboxes when accessing exchange over various supported protocols. Following are the main steps for configuring service account.

  • Setting up service accounts on Exchange server
  • Configuring a service account on Exchange server

Setting up service accounts on Exchange server

For the purpose of Exchange Notification Proxy (ENP), Microsoft’s Exchange Web Services (EWS) protocol is used to access mailbox messages.

For example service account is assigned to the following role:


The EWS sends requests with the credentials of a single service account which includes an .XML key.


<t:RequestServerVersion Version="Exchange2013" />

<!-- The following causes the request to run as [email protected] -->



<t:SmtpAddress>[email protected]</t:SmtpAddress>




This allows a single account to access the mailbox of other accounts.

Configuring a service account on Microsoft Exchange Server

To configure service account on EWS follow these steps:

  1. In the Microsoft Exchange Management console, open a browser and type in URL. For example:https://<hostname>/ecp
  2. Log in as an Admin, go to Mail > Options > Manage My Organization > Roles & Auditing> Mailboxes and create a new Role group.
  3. Add the applicationImpersonation role to the group.
  4. Add members to the group.
  5. Click Save to finish.

For more information on configuring service account on Microsoft Exchange server, see Microsoft documentation

Setting up Standalone Sentry as an Ivanti Email+ Notification Service

You can set up a dedicated Standalone Sentry as an Email+ Notification Service. This capability allows you to configure multiple Exchange servers to provide notifications for VIP accounts in Email+.

This feature requires UEM servers, Cloud Notification Service (CNS), Standalone Sentry, and Email+. Applicable to iOS only, the Email+ Notification Service cannot be combined with ActiveSync or AppTunnel. Email+ Notification Service requires Sentry 9.8.5 and Email+ 3.13.0 through the latest supported versions. (Content Notification System is automatically upgraded). For more information, see: “Standalone Sentry Email Notifications” section in the Ivanti Sentry Guide for Ivanti EPMM
