Hey guys, so long story short, I have a Galaxy s7 that wont sync the calendars from an exchange account. However, this same account will sync up on a different device. i have tried deleting the account and reapplying it, i have tried flipping the sync option off and back on with the calendar. at this point it gives me the error : sync is currently unavailable, please try again later. any help here would be greatly appreciated. Thanks in advance.
