This seems to be an issue that is years old but I had a self-created folder that used to live on the server.  A couple of days ago it completely disappeared.  By that i mean that I can't find the folder and for that reason I can't file anymore messages in it.  However, it still exists because I can find messages that I previously placed in it.  But because Outlook doesn't give the directory info I can't tell where the message is.  Spotlight doesn't work.  I have looked at every folder that has a sub-folder, every one.  Still can't find the missing one.   Spotlight doesn't find it.  What to do?
