Delegated calendar
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 Delegated Calendar option in Email+, configure the calendar_delegation value in enabled_features key value pair.
Microsoft Exchange server provides Reviewer, Editor, and Author level permissions, in the Email+ app delegated user can create, view edit and remove calendar events according to permissions given by the owner. The delegated user can view event related updates on the Email+ app with this permission.
The following table displays the different delegation permissions and the actions they can perform:
| Permission level | Action allowed |

To configure delegation, configure the following key-value pairs:
- Add calendar_delegation value to enabled_features key-value pair to add the Add Delegated Calendar option in the Email+ app.
- Add email_ews_host key-value pair with EWS host value as FQDN to provide access to EWS server.
- Add ews_min_allowed_auth_mode key value pair to enable basic, certificate based authentication, and modern_auth authentication methods to the exchange server through EWS protocol. If Email+ is configured with eas_min_allowed_mode KVP as Modern Auth, add ews_min_allowed_auth_mode KVP with modern_auth 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.
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 Delegated 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.
The calendar owner delegates the calendar from the Microsoft Outlook on the web (OWA). For more information on delegation, see Microsoft documentation.
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 Delegated Calendar option from the Email+ app by removing calendar_delegation value from the enabled_features key value pair.
