Export calendar to devices

Starting from v. 10.0 there is the possibility to synchronize calendars from the 'My Calendars' section using the CalDAV protocol. When you synchronize a calendar, all the changes made to existing events as well as newly created events will be displayed both in the third-party calendar for which the synchronization is enabled and in the portal web interface.

Please note that the synchronization via the CalDAV protocol is supported for new calendars only, i.e. for the calendars created after updating the portal to version 10.0. If a calendar has been created in an earlier portal version, the CalDAV synchronization will not work.

Starting from v. 10.5, it's also possible to export calendars from the Other Calendars section. The CalDAV calendar is created when trying to get a link for export (Export and Sync -> CalDAV). When exporting a calendar to devices, access rights to the calendar and events remain unchanged (for example, events from the Users' birthdays calendar cannot be changed, but you can modify events from the shared calendar if you have been granted full access to it).

Export a calendar to your Android device

Android devices do not have the built-in support for the CalDAV synchronization. To export a calendar, first you need to install a third-party app on your device, for example, OpenSync

When the app is installed, open it.

If you are going to export not only calendar events, but also todos, you'll also need to additionally install the OpenTasks app on your device to be able to export todos. When you launch the OpenSync app for the first time, the corresponding notification message appears. Click the Install OpenTasks to install the app.

In the OpenSync app, click the Plus button in the lower right corner to add a new account.
Select the Login with URL and user name option.
Specify the account settings:
- Base URL - specify your portal address + /caldav/, for example,
  https://portalname.onlyoffice.com/caldav/
- User Name - specify the email address that you use to access the portal
- Password - specify the password that you use to access the portal
Press Login in the lower right corner.
Then press Create account.
In the notification bar, a notification will appear informing that the app requires permissions. Tap the Request calendar permissions button, then provide the corresponding permissions by tapping the Allow button.
If you are going to export todos, you'll also need to provide permissions for the OpenTasks app. Tap the Request OpenTasks permissions button, then provide the corresponding permissions by tapping the Allow button. When you launch the OpenTasks app for the first time, you'll also need to provide permissions via the app interface.
In the OpenSync app, tap the added account (by default the email address is used as the account name).
All calendars from the My Calendars section of your account that support the CalDAV synchronization will be imported to the device and displayed in the CalDAV list. Check the calendars that you need to display in the default calendar app on your device.
If you are going to import todos, you'll also need to enable the Todo_calendar by checking it in the list in the OpenSync app.
Open the default calendar app on your device. Refresh the calendar by tapping the menu button in the upper right corner and selecting the Refresh menu item. After that the events from the exported calendar will be displayed in the default calendar on your device.

If you are going to import todos, open the OpenTasks app and refresh the todo list by tapping the menu button in the upper right corner and selecting the Refresh menu item. After that the Todo_calendar will be displayed within the OpenTasks app.

- Password - specify the password that you use to access your account on the portal
The settings will be verified and saved.

- Tap Advanced.
- In the Account URL field the URL address must be specified in the following form:

  Correct the URL by adding login@example.com@portalname.onlyoffice.com/
  
  Where login@example.com is the email address that you use to access your account on the portal
- Return to the previous screen and save the settings by tapping Done.
  After you press the Done button, return to the advanced settings and verify once again that the data is specified correctly.

After that the exported calendar will be available in the calendar list and the events from it will be displayed in the default calendar on your device.
