When you attempt to view the folders on an Internet Mail Access Protocol (IMAP) server in Outlook Express, the folders may be missing.
This behavior can occur if the Folders.nch file is missing or damaged.
To resolve this issue, rename the Folders.nch file, and then refresh your folder list. To do this, follow these steps:
The Folders.nch file is a local file that stores a cache of all folders on a server. Your subscriptions are stored on the IMAP server and are not affected if the Folders.nch file is missing or damaged. Refreshing the folder list creates a new Folders.nch file. It is not necessary to subscribe to all folders again.
