Setting up Microsoft Outlook with CalDAV Synchronizer

CalDAV Synchronizer is an Outlook extension that you can use to sync events in your calendar. In this guide, we show how to set it up in Outlook for Windows.

Note: CalDAV synchronization is not supported on Outlook for Mac.

• Step 1 - Download and install extension
• Step 2 - Open Webmail and copy the CalDAV URL
• Step 3 - Open Outlook and click CalDAV Synchronizer
• Step 4 - Click Synchronization Profiles
• Step 5 - Add a new profile
• Step 6 - Select CalDAV folder in Outlook
• Step 7 - Enter your server settings
• Step 8 - All done!

Note: You can't use the CalDAV Synchronizer in combination with Mobile Sync (Exchange ActiveSync), on the same email account.

Mobile Sync already syncs your primary calendar automatically. If you want to synchronise more than one calendar, we recommend setting up your account with IMAP in combination with CalDAV Synchronizer.

Step 1 - Download and install extension

To sync your Webmail calendar in Outlook you need to download and install the extension Outlook CalDAV Synchronizer.

After you have installed it on your computer, you need to restart Outlook. The extension will then be visible in Outlook as a tab (in the blue ribbon at the top).

Note: Both Outlook and the CalDAV Synchronizer extension are third-party products. This means that one.com has no control over any changes or updates that may cause it to stop functioning.
