What Is the Outlook Error 0x8004010f?

When you configure MS Outlook using an Exchange or IMAP-based email account, an Offline Storage File (OST) is created on your local system. A Personal Storage Table (PST) file is also created when you add a POP account to Outlook.

These Outlook data files (OST and PST) contain a synchronized copy of all mailbox data from the email server. In a nutshell, an OST or PST file is a local copy of the user’s mailbox. It stores all mailbox items, including emails, attachments, contacts, notes, and calendar items.

OST allows users to access Outlook even if the system is down or the Exchange server is unavailable due to technical issues or maintenance. Users can continue working on Outlook without interruptions in such cases. Furthermore, any changes they make to the account or send an email message from Outlook are saved locally in the OST file. The adjustments are synced with the mailbox once the system connects to the Exchange server or the server goes online.

However, there may be times when users encounter errors when attempting to access their mailbox data via the Outlook data file. These problems could be caused by a faulty synchronization between Outlook and the email server, or by issues with the OST or PST file. Problems with the OST or PST file frequently cause mailbox access and send/receive errors.

Here are some of the message notifications you might encounter along with the Outlook 0x8004010f issue:

  • Sending reported error (0x8004010F): ‘Outlook data file cannot be accessed.’
  • Receiving reported error (0x8004010F): ‘Outlook data file cannot be accessed.’
  • 0x8004010F: The operation failed. An object could not be found.

When the error code is 0x8004010f 00000000 00000000 or 0x8004010f-0x8004010f-0x000501, you don’t have to panic. These are just different versions of the Sending Reported Error 0x8004010f.

The article is specifically designed to assist you in understanding why you received the Microsoft Outlook 0x8004010f error and how to resolve it.

Reasons Why You’re Getting 0x8004010f Outlook Data File Cannot Be Accessed Error

The Outlook 0x8004010f error- “Outlook data file cannot be accessed” will appear on the screen if a user does not have access to the OST file. As we’ve mentioned, the problem can be due to faulty or incomplete synchronization between Outlook and the Exchange server.

The OST or PST file is vulnerable to damage due to a variety of factors. These include corruption as a result of oversizing; a virus attack; and an accidental or forced shutdown, among other things. While these are the most common causes of OST and PST file corruption, human error can also result in the issue.

Most of the time, this is a MAPI error that occurs while synchronizing an offline address book (OAB), sending/receiving emails, or downloading OAB files.

According to Microsoft, the corrupted Outlook profile is to blame for this problem. To resolve the issue, try creating a new profile. However, that is not always the case. The following are the primary causes of the error:

  • Exchange data – If Outlook is set to use the cached Exchange mode, then Outlook’s corrupt cached data could be the source of the Outlook data file access problem.
  • Corrupt/damaged Office installation – If your Office suite installation is corrupt, you may experience Outlook file access problems.

Other factors you need to rule out include:

  • Incorrectly configured Outlook or a corrupted Outlook profile
  • Poor network connection
  • Using the Shared Mailbox to send/receive emails
  • Changes to the machine’s OST file location
  • Damaged Outlook program files
  • Inadequate read/write permissions
  • The primary account is not configured with the OST file
  • Firewall settings

How to Resolve the Outlook 0x8004010f Error on Windows 10/11

You can fix the Outlook error in a variety of ways, depending on the underlying cause. However, before you proceed, make sure to back up your Outlook data and run a scan using a PC repair tool like Outbyte PC Repair to get rid of junk files in your Outlook folder.

Once you’ve made your preparations, you can safely proceed with the solutions below:

Fix #1: Relaunch Outlook

A simple restart can sometimes resolve issues with programs and the system. So, restart Outlook or your system and then check back. Check the internet connection as well. If this does not resolve the Error 0x8004010F, try the next method.

Fix #2: Launch Outlook as an Admin

If Outlook does not have administrator privileges to access the directory containing the Outlook data file, this can result in the error. In this case, launching Outlook as an administrator may resolve the issue. Keep in mind that some Outlook features (such as Outlook search) may not function properly when launched as administrator. However, the user can launch the Outlook client in normal mode after successfully adding the Outlook data file.

  1. Close Outlook and all of its associated processes in the system’s Task Manager.
  2. Now, go to Windows, look for Outlook, right-click it, and choose Run as Administrator.
  3. Then, check to see if the data file cannot be accessed issue has been resolved or if the user is able to select the required Outlook file.
  4. If that doesn’t work, go to Windows, look for Command Prompt, right-click it, and choose Run as Administrator.
  5. Now, run the following command if the Outlook data file is in PST format. Otherwise, change the extension in the command to match the file. icacls *.pst /setintegritylevel m

If that doesn’t work, see if disabling UAC on the affected machine (at your own risk) solves the problem.

Fix #3: Double-Check Your Outlook Account

Check that your account settings are correct and that the Exchange server is up and running. You can use Outlook Web App to check this (OWA). Try logging in through OWA. This will help you determine if there is a temporary connection problem. Also, ask the administrator if they’ve changed any server settings in your Outlook account that you need to change.

However, if you successfully login to OWA, there could be another problem. To resolve the Outlook 0x8004010F error, use the methods listed below.
