Calendar Synchronization | Online Help - Zoho CRM

Setting Up Calendar Synchronization via CalDAV

Gone are the days when you had to log in to Zoho CRM every time you wanted to check your work schedule for the day. You can now receive alerts about the next staff meeting on your iPhone or even your Apple Watch, without having to log into Zoho CRM!

Zoho CRM supports Calendar synchronization with any iOS device (iPhone, iPad, MacBook as well as Apple Watch) via CalDAV configuration. The result – any event that you create in Zoho CRM will be synchronized with your iOS Calendar and vice versa.

Here, an event called “Product Launch” created on an iPhone seamlessly synchronizes with Zoho CRM as well as the Apple Watch. Here are some screenshots of alerts on the iPhone, Apple Watch as well as Zoho CRM.

Manage events efficiently

By enabling CalDAV configuration on your iOS device, you can manage all your events efficiently. Let’s say CalDAV pushes events from Zoho CRM to your iPhone. This way you can see both personal events as well as your business events on your iPhone Calendar. If you find that a lunch date overlaps with a staff meeting, you can quickly reschedule the events from the iPhone based on your priorities. You don’t have to log back into Zoho CRM to edit an event.

CalDAV for multiple iOS devices

You can configure CalDAV on more than one iOS device including the iPhone, iPad, MacBook and iPod Touch. As for the Apple Watch, there is no separate configuration involved. Pairing the Watch with an iOS device would be sufficient to get the alerts on your Apple Watch. The events will be synchronized between Zoho CRM and all the devices in which the CalDAV configuration has been enabled. So perhaps the next time you are driving and unable to check your iPhone, all you have to do is tilt your wrist to know the day’s schedule from the Apple Watch!

Work offline

What’s more, you can also create or edit events on the phone when you are offline. When you are back online, your events are automatically synchronized in Zoho CRM.

In order to start using Calendar Synchronization via CalDAV in your iOS devices, you must first

  1. Enable CalDAV access in Zoho CRM

Configure CalDAV Account in an iOS Device

This CalDAV Calendar Synchronization is currently compatible only with iOS devices. This includes the iPhone, iPad, iPod Touch, Apple Watch and MacBook. Note that the CalDAV configuration has to be enabled on each iOS device separately, except on the Apple Watch.

As for the Apple Watch, it has to be only paired with the iPhone for calendar synchronization. You will be able to receive event alerts on the Apple Watch and not create/edit events in the Apple Watch.

The procedure to configure CalDAV is the same for all iOS devices. The instructions for CalDAV configuration on the iPhone are mentioned below.

When you use third party apps, please note that the Server address will differ. In such a case, please contact our Support team for the correct configuration settings.
