I just switched from google.  I use Outlook on my iphone 6 plus and am not able to view my calendar via the IMAP method (only email).  I tried setting it up via "Exchange" on Outlook for IOS and entered the proper server name: "msync.zoho.com" but always get an error message "Unable to log in  Please check you email address and password and try again."

I have entered the correct credentials and no luck.  I also have read the forum here regarding this issue but have had not luck resolving this.  Can you please assist me?
