Some of your calendars don't sync with Windows Phone

This article describes the limitations that you may encounter when syncing your calendars from Exchange and Google with Windows Phone.

Windows Phone can concurrently sync calendars from several different services (for example, Windows Live, Exchange, and Google). Whereas the phone syncs all calendars from Windows Live, it won't sync all of your calendars from Exchange or Google. However, Windows Phone can sync multiple calendars from Google, but it requires some additional setup.

Here's what Windows Phone will sync:

Your phone will only sync the primary calendar from Exchange or Google, by default. The primary calendar is usually the first calendar listed in any given account, one that you might have named yourself, or an email address.

In this Google example, the primary calendar "Personal" is the first one listed under My calendars, and the one that will sync to Windows Phone, by default.



In this Exchange example, the primary calendar "Calendar" is the first one listed under My Calendars and the one with an email address next to it, and the one that will sync to Windows Phone.



Here's how to configure Windows Phone to sync multiple Google calendars:

To configure your phone to sync additional shared calendars, subscribed calendars, or secondary calendars for your Google account, follow these steps:

1. From the Start screen on your Windows Phone, flick left to the App list, and then tap Internet Explorer

   , located at the bottom of the screen, and then tap Settings.
3. Locate Website preference, and tap Mobile version from the drop-down list. Press the back button on your phone to return to Internet Explorer.
4. Tap the address bar, and enter http://m.google.com/sync. If this is your first time visiting, tap Sign in with your Google Account.
5. As soon as you're signed in, select your phone from the device list.
   
   Note if you have multiple devices and don't know which one to select, yours should be listed as WindowsPhone and have a "Last sync" date value that is recent.
6. Under the headings My Calendars and Shared Calendars, tap the check box next to each calendar that you want to sync with your phone. Tap Save. Note the additional calendars selected will show up after your phone's next sync with Google (every 30 minutes by default). 
7. Start a manual sync with Google to see your new calendars by going to the Start screen on your Windows Phone. Flick left to the App list, and then tap Settings
