Yesterday I changed what folders are visible in IMAP for my Gmail accounts. The only ones I show now are: inbox, sent, draft, trash and starred. I am now getting a duplicate folder name error 1025 in /Gmail/Spam/. I have hidden those folders from IMAP and in the case of the one below the root, I removed. Under advanced/folders I said move junk mail to trash. My Outlook version is 14.2.3. Apple mail does not have this problem nor does Outlook for Windows.
