Using subfolders in Outlook with IMAP accounts Print

  • 4

Several IMAP server implementations, including (older versions of) Horde, work from the Inbox folder as a root folder. New folders can then indeed only be created directly under the Inbox folder which can interfere with Outlook’s internal folder structure.

The result is that you don’t have a Junk E-mail folder and that this feature doesn’t work.

To solve this, you can set the “Root folder path” option in your account settings.

Before - Configure a root path if your IMAP folder structure falls under the Inbox folder.
