I'm able to add multiple g-calendars from multiple accounts, but it appears that only the root calendar is synced with Windows 8's Metro Calendar app. Is there a way to sync all gmail calendars?

  • It might not be possible. You could try adding the other calendars on a single calendar, that should depending on the share settings of the other calendars, do what you want.

From a question I asked:

Someone posted a working solution on Microsoft Answers:

  1. Download User Agent Switcher from the Chrome Webstore
  2. Select an iOS device
  3. Go to https://m.google.com/sync/settings/iconfig/welcome?source=mobileproducts
  4. Deactivate Javascript in Settings (Show advanced settings, Privacy > Content settings > Do not allow any site to run JavaScript)
  5. Click your Windows Mail device
  6. In the URL change supportMultiCalendars=false to supportMultiCalendars=true
  7. Submit URL (Press Enter)
  8. Check the boxes for the calendars you'd like to sync
  9. Save
  10. Readd your Google Account to your Windows Calendar app. It now works.
  11. (Re-enable JavaScript in Chrome)

    Strange, it works for me and at least 5 others. I wonder if the Google Calendar people caught on. Commented Sep 4, 2012 at 14:02

    Strange, not working for me. I can see the other calendars on my Windows Phone but not on Windows 8.

At the moment, this probably can't be achieved. This same Question has been asked on MS Support and they have replied with a no.


Syncing Multiple Google calendars with New UI Calendar app


Currently per Google's request for bandwith, Calendar App only Sync root calendar.

Developers on both sides are working on this issue to improve accessibility on this.

Another thread from the Ms Support


How to sync multiple Gmail Calendars using the Mail, Calendar, Messaging and People App?


You have multiple calendars in your Gmail calendar but only one of them syncs with the Calendar app and you want to know how to sync all the others calendars to the Calendar app. Please note that currently per Google's request for bandwidth, Calendar App will only Sync root calendar. Developers on both sides are working on this issue to improve accessibility on this.


Easiest fix is just to import each Google Calendar into a hotmail account. Then when you add this account to the Windows 8 Calendar app not only do they all appear, but they are still organized by color.

    If the Google Calendar is modified are the changes reflected by the Hotmail account? Commented Nov 2, 2012 at 6:36

This seems to have changed again:

  1. Using Google Chrome, ensure you are signed in to Google
  2. Add User-Agent Switcher from the Chrome Web Store
  3. From the face icon that appears in the toolbar select iPhone
  4. Go to https://m.google.com/sync
  5. All of your devices should now appear (Windows 8 is known as WindowsMail)
