Outlook error 0x8004010f is one of the error messages that might make a user of Outlook feel upset. It’s common when using Outlook 2010 and 2013 to send and receive emails. What’s the meaning? It says, “Outlook data file can’t be opened.” You might also wonder why this is happening and how to fix it immediately. This article will help you figure out why you’re getting the  error and how to fix Outlook error 0x8004010f.

What Can Cause Outlook Error 0x8004010f?

When you use MS Outlook, all your mailbox data is stored locally on the Offline Storage Table (OST) file. The OST file acts as a copy of the user’s Exchange mailbox because it saves all of the account’s records that are stored on the server on the local computer.

The main job of the OST is clear when the Exchange server is down because of technical problems or maintenance. If this happens, an Outlook user can keep working with the OST file locally, and once the Exchange server is up and running, changes to the account can be synchronized with the Exchange account.

The Outlook 0x8004010f error, “Outlook data file cannot be accessed,” will show up on the screen when a user can’t access the OST file because Outlook and the Exchange server haven’t been synchronized properly. Here are the most important reasons for the mistake:

  • Offline Storage file corruption
  • Outlook profile is broken, or the settings are wrong
  • The OST file has moved.
  • After upgrading Outlook, make a copy of the old OST file used by the old version.

Now, let’s talk about how to fix error 0x8004010f.
