Error code 0x8004010F is an Outlook error that have plagued Windows users for some time. If MS Outlook is used while connected to the Exchange server, all mailbox data on the server is stored locally in a file called OST (Offline Storage Table) file. This file can be considered as a copy of the user’s Exchange mailbox, as it stores all account records locally on the server.

The main role of this file comes into play when the Exchange server fails due to technical problems or maintenance work. In such cases, users can continue to work locally with the OST file without interruption, and any changes they make to the account are merged with their Exchange account as soon as the server reappears.

When you try to send or receive emails in Outlook 2010, you can receive one of these error messages:
