Hi all,
Someone has happened to this case, I have a 5s iphone with IOS 9 and is configured for the mail service with Novell Data Synchronizer yesterday the name of the owner of the account was changed without anyone handling, I had to delete the account in the Novell Data Synchronizer console to re-create and present the correct user name

ok - Danny Landi dlandi@pruebas.com ok
bad - Jose Munoz dlandi@pruebas.com - X

Anyone have a possible cause
