I have confluence cloud. I am trying to edit a word document using the edit in office button. When it tried to download, a windows security window opens prompting me for credentials. Neither my windows logon nor my atlassian cloud logon work and it won't allow the file to download. This occurs both on Firefox (32.0.3) and IE11 (11.0.9600.17498). I have not found any related questions that address this specifically.
