yes, I'm losing my email account passwords when CC was running.
I don't know where Outlook (desktop app) is saving my passwords but if I just analyze it in CC then I get different entries in "All Users\clienttemplates.content.office.net", "All Users\odc.officeapps.live.com", "All Users\officeclient.microsoft.com" and "All Users\p.pfx.ms"
in total I get a count of 67 files.
all the time I am talking about the desktop app of Outlook in Office 365.
