Help with Set up MS Exchange ActiveSync on Android (Galaxy S3)

Help with Set up MS Exchange ActiveSync on Android (Galaxy S3)

1) I get the error "Incorrect user name or password" when I enter "\ admin@davidleistmemorial.org" into the "Domain\username" box.  (I'm sure I've entered the right password.)

2) Since the instructions say the domain can be anything (for systems where it is mandatory), I tried entering "anything\admin@davidleistmemorial.org" into the "Domain\username" box, and I got the error message: "Server error occurred. Check your username and password, and try again."

I have gone through Zoho's instructions at http://zsync.zohosites.com/Android.html meticulously.  I know I am entering everything as instructed.  (I entered "msync.zoho.com" in the Exchange server box, used correct passwords, etc.)

Is there something I have to do at the login at "mail.zoho.com" to authorize remote sync?  I can't understand what I'm doing wrong.

Any suggestions would be appreciated.  Thanks in advance.
