How to Rectify ‘0x800C012E,5’ Error of Outlook Express

The ‘Store Folder’ of your Outlook Express is the storage house of your entire mailbox data including emails, contacts, newsgroups, etc. However, all these mailbox folders are not scattered all over the ‘Store Folder’, instead they are kept in specific DBX files. That means inside your ‘Store Folder’ you have separate DBX files for Inbox, Outbox, Sent Items, etc folders as Inbox.DBX, Outbox.DBX, and so on. Therefore, if in case this folder gets corrupt, then the abnormal behavior in your Outlook Express application is seen and you will lose access to your mailbox data as well. Such situations generally result in an error message when you try to extract data from ‘Store Folder’ or try to open it.
