Citation is formatted wrong in EndNote

When I insert citation with multiple authors (with EndNote online in word 2013) endnote puts an ‘e’ instead of an ‘&’ between the author names. How can I edit this for the whole document? 

This is defined in the output style that is selected in the word processing ribbon/menu of endnote online?  Which output style have you selected?  That seems pretty strange, as those are not editable by users in Endnote Online?  Do you have an Endnote Online  administrator?  

I have selected the output style to be ABNT (Author-Date) in word and I do not have an Endnote online administrator… any suggestions to what i can do? 

That is a Brazilan output style – so it is using a e instead of “and” in the citation template.  You should select an english output style?  Like (Author, Date) or Cell?
