Long story short, Google dropped support for Exchange ActiveSync (EAS) connections in early 2013 and that's why the Calendars won't sync. But email and contacts do. It's stupid. I spent a bit of time figuring this out earlier today because when you search on this topic, a lot of the information is out of date or just plain wrong. Basically you have two options. Just ignore the 8.1 Calendar App and put a shortcut to Google Calendar on your Start, or... You can sync the 8.1 Calendar TO Google Calendar, but not the other way around. Basically you can see all your appointments like you want to, but for changes/additions/deletions you have to go to Google Calendar. Yeah it's a pain but it's better than nothing, and the 8.1 Calendar will keep updated with whatever you change in Google Calendar. Also you will need a free Outlook.com email account (this used to be Hotmail.com). But that's a good thing, Outlook.com is pretty sweet and i bet a lot of people already have one. 1. open Google Calendar 2. click the "gear" icon in the top right -> Settings 3. click "Calendars" at the top 4. choose your calendar (you probably only have one and it has your name on it) 5. scroll down to "Private Address" (not Calendar Address) and click on ICAL 6. copy that shortcut, you'll need it 7. Open Outlook.com and login 8. click the arrow at the top and pick "Calendar" 9. click "Import" at the top 10. click "Subscribe" on the left 11. in the Calendar URL field, paste in the link that you go from your Google Calendar 12. click Subscibe 13. *at this point the Outlook.com calendar should start populating with your Gmail Calendar stuff... be patient if it takes a bit of time 14. On your Surface, go into your Calendar App 15. swipe left to get the Charms sidebar -> Settings 16. Accounts 17. Add an Account 18. Outlook.com 19. type in your username and password for Outlook.com 20. Connect YOU'RE DONE!!, again, be patient, it takes a bit of time for the Calendars to sync. You can now SEE all your Google Calendar stuff in 8.1 Calendar... you just can't change it, or at least if you do it won't sync so it's best not to. Hope i didn't leave anything out. Good luck!!
