I have a user of Outlook 2013...Out of the blue, folders that were created to separate mail and some contacts and/or some contacts info has disappeared. PLEASE HELP!!!
You're going to need to provide some additional info like
#1 - Type of email account involved (POP3, Imap, MAPI/EAS, Exchange etc)?
#2 - Where exactly did you create these "extra folders" - in the folder tree of the email account involved or in another data file/account?
#3 - Do you sync your Outlook data with any other device?
It's been my experience that when folders disappear the reason is most likely to be that they were accidentally dragged someplace else. It's really easy to do. If you have too many folders to manually search, there are a number of vb scripts available online that will give you a text file listing of your folders which you can then search using a text editor or Word.
