As explained on the Synology official website, CalDAV Server (Synology NAS in our case) is a calendar management application that allows you to easily sync and access your calendars. Calendar events on the Synology network-attached storage (NAS) can be accessed from any CalDAV client, should it be a cellphone (iPhone, iPad, iPod touch) or a computer. Refer to the following article for more details: How to host a calendar server using the Synology NAS.

In this article we’ll show you how to securely manage your calendars sourced from the Synology NAS using CopyTrans Contacts. Manage you Synology calendars easily

With CopyTrans Contacts, you can access and manage your NAS calendars and move them between your iOS devices, such as iPhone, iPad, or iPod touch. You can also transfer your Synology calendars between iCloud, Gmail and Outlook accounts.

In our guide, we use Synology Model DS713+ with the operating system DSM 6.0.2.

Installing WebDAV Server and enabling CalDAV

  1. Open the Package Center from your desktop: Set up caldav on the computer

  2. Find the tab Utilities from the list on the left-hand side > WebDAV Server > Install: install the WebDav Srver on your PC

  3. Wain until the WebDAV Server gets installed and automatically started. After this, you can open the app.

  4. For security reasons, it is recommended to enable HTTPS in the application and change the port. By default, we use the secure port 5006. Click Apply: Enable https for synology calendar

  5. Now choose Calendar from the left-hand pane. Here you can enable CalDAV and apply the changes: Enable CalDav for synology calendar

  6. Create a new calendar. Tap on the View Calendar List button > Add. Enter the name of your calendar(s) and choose the destination. Click OK to confirm: Configure synology nas CalDav

  7. Remember the calendar address. Hover the mouse over the calendar location to view the full URL address of the calendar: Configure CalDav NAS synology

Access Synology calendars over the internet

Now let’s make sure that your calendars sourced from the Synology NAS can be accessed over the internet.

  1. As an administrator, navigate to the Control Panel > Info Center > and open the Service tab.

  2. Choose WebDAV from the Packages list: Allow WebDav Server through firewall and test the internet connection

  3. The service should be enabled. Check the box in the Allow through firewall column. Now apply the changes and test the connection again. In the far right column, the “Internet accessible” status will appear: WebDav is internet accessible

Set up port forwarding on a router:

  1. Navigate to the administrative section of the router.

  2. Log into your router and find the appropriate menu item.

  3. Forward secure HTTPS requests to TCP port 5006 from outside to the port 5006 on Synology (local IP address).

  4. Test the connection on Synology NAS again.

Set up Synology CalDAV on your iPhone

  1. If you are running iOS 11, open the Settings app > Accounts & Passwords > Add Account > Other > Add CalDav Account.
    If you are running iOS 10, navigate to the Settings > Calendar > Accounts > Add Account > Other > Add CalDAV Account.
    For iOS 9, 8, 7, go to the Settings app > Mail, Contacts, Calendar > Add Account > Other > Add CalDAV account.

  2. You’ll be requested to type in the server address (external IP address of Synology NAS), username, and password. We entered Synology to the Description field. Confirm by clicking Next: Configure CalDav on your iPhone or iPad

  3. Voilà! The account has been successfully added. Your device itself will select the secure port. You can check this in the Advanced settings of the newly added account.

  4. Now you can find your Synology calendars in the Calendar app on your iPhone. If you want to view the Synology calendar only, navigate to Calendars on your device: Add Synology to your iPhone Calendars

  5. Choose Hide All Calendars, tick the Synology calendar and click on Done to confirm: View Synology calendar on your iPhone or iPad
