Not sure if this is a Yosemite problem or general problem. I changed the email address on my iCloud account from Google to Outlook(I've learned to never do this) and all kinds of hell has popped up. I'm not able to remove the gmail associated email from my iCloud I get this issue: Your iCloud account couldnt be removed at this time.Turn off all iCloud services and try again. The problem is all the services are greyed out and no way to uncheck the "Photos" one. Anyone with suggestions?
