To configure Shared Calendar on Android AppConnect or Android Enterprise, configure the following key-value pairs or restrictions:

  • Add calendar_delegation value to enabled_features key-value pair or calendar_delegation value to Optional Features restriction to add the Add Calendar option in the Email+ app.
  • Add email_ews_host key-value pair or Exchange host for EWS restriction with EWS host value as FQDN to provide access to EWS server when the values for email_exchange_host key-value pair or Exchange host restriction are not fully qualified domain name of the exchange server.
  • Add ews_min_allowed_auth_mode key value pair or EWS Authentication Mode restriction to enable basic, modern_auth, and cert_based authentication methods to the exchange server through EWS protocol. If Email+ is configured with eas_min_allowed_mode KVP or Authorization mode restriction as Modern Auth, add ews_min_allowed_auth_mode KVP with modern_auth or EWS Authentication Mode restriction with Modern Authentication value to enable modern authentication method to the EWS server.
  • If EWS server is not accessible publicly (located in private network), then VPN should be configured. For more information see, Configuring Email+ with AppTunnel for Android AppConnect and Configuring Email+ with Ivanti Tunnel for Android Enterprise

The Email+ app sends a notification when access to Shared Calendar is canceled by the calendar owner. The user receives notification when the Email+ app is launched or is running in the background. The Shared Calendar is removed from the Email+ app.

The sync period for all existing events for the Shared Calendar is set to a duration of one month. Events older than a month are not synced.

Adding shared calendar

In the Email+ app, go to Calendar > Add Calendar option and enter the calendar owner's email address. Select the calendar owner to add the shared calendar. You can assign a color to the shared calendar to differentiate between assigned calendars.

Disabling shared calendar feature

The admin can disable the Add Calendar option from the Email+ app by removing calendar_delegation value from the enabled_features key value pair or from the Optional Features restriction. For more information on the supported key-value pairs and restriction, see Key-value pairs for Ivanti Email+ (Android AppConnect) and App restrictions descriptions for Ivanti Email+ (Android Enterprise) sections.

For more information on Email+ configuration, see Email+ configurations supported for Delegated Calendar section in Delegated calendar .

Microsoft limitations

The shared calendar has following Microsoft limitations:

  1. Reply event and Reply all options are available but reply mail cannot be sent. The message is moved to Drafts and error message is displayed.

  2. The 'Invite people' field is blocked and proper notification is displayed.

  3. For Exchange server: If Shared user has ‘Create items’ permission, but do not have the ‘Edit own’ or ‘Edit all’ - it is not possible to create invite with attendees. So, in Email+ when user tries to create new event the ‘Invite people’ field is blocked and proper label is displayed.

  4. As Exchange 2013 server will be deprecated in April, the Shared calendar feature is not supported  by Email+ 4.6.0 on this server.

  5. Email+ 4.6.0 does not provide support for the following permissions:

    1. For Exchange server: 'Time, Subject, or Location', 'Free or Busy time'

    2. For Office 365: 'Can view when I’m busy', 'Can view titles and locations'.
