Ivanti Email+ supports delegated access for Calendar. The delegated calendar option enables the calendar owner to assign their calendar to a delegated user within the organization's exchange Global Address List (GAL). To enable the **Add Calendar** option in Email+, configure the **calendar\_delegation** value in **enabled\_features** key value pair or in **Optional Features** restriction.

Email+ supports delegated calendar permissions similar to Microsoft Exchange server such as Reviewer, Editor, and Author level permissions. The delegated user can view events related updates on the Email+ app with these permissions.

:::hint{type="info"}
The Email+ app does not display private events, all private events in delegated calendar are hidden.

The following table displays the different delegation permissions and the actions they can perform:

| Permission level | Action allowed                                                                                                                                                                                                                                                                                                                                                                                                  |

To configure delegation 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 Delegated 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](docId\:EdeSgPawU9zcIthBHbN-N) and [Configuring Email+ with Ivanti Tunnel for Android Enterprise](docId\:ozbLCrM6ggYDjN35XIkvc)

When a calendar is delegated, a system generated mail is sent to the delegated user with details of the calendar owner. The calendar owner has the ability to assign or deny access to the delegated calendar.

### Adding delegated 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 delegated calendar. you can assign a color to the delegated calendar to differentiate between assigned calendars.

:::hint{type="info"}
The calendar owner delegates the calendar from the Microsoft Outlook on the web (OWA). For more information on delegation, see [Microsoft documentation](https://support.microsoft.com/en-us/office/allow-someone-else-to-manage-your-mail-and-calendar-41c40c04-3bd1-4d22-963a-28eafec25926).
:::

The user can manually remove the delegated calendar from the Email+ app. If the access to the deleted calendar is available, then user can again add that delegated calendar.

When the calendar owner removes access to the delegated calendar, Email+ receives "**Delegated Calendar access has been denied**" notification when the Email+ app is launched.

### Disabling delegated 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)](docId\:fQckqTshSkVVfVl0NWFE3) and [App restrictions descriptions for Ivanti Email+ (Android Enterprise)](docId\:KlQsw-tcKAeEwRj5AzG1A) sections.
