[Solved] Outlook Error 0x8004010F in 2010 or 2013: Data File Cannot Be Accessed

If you are using outlook.com as your email, it will connect to the Exchange server. All the mailbox data of your account are stored locally in a file called Offline Storage Table (OST) or Personal Storage Table (PST) file.

It will replicate all the database records of the user’s Exchange mailbox. The Exchange Server encounters issues such as Internet connectivity or maintenance, which activates the main purpose of this file. However, you can continue to work offline because the OST file resides locally.

When the Internet is restored, you can update them to sync with the server.

Sync issues between Outlook and Exchange cause problems. It could be a problem with a corrupt PST (Personal Storage Table) file also. In many of the cases, the mailbox access errors within the OST file will cause error 0x8004010F.

How to Fix Outlook Error 0x8004010F in 2010 or 2013

The following are the common solutions.

New Outlook Profile

A default profile is created when you install Outlook and add your first email account. Sometimes if this profile is corrupted, you can face this issue.

In this case, you can just create a new profile.

1. Control Panel (View by small icons) > Mail
2. Click on “Show Profiles.”
2. Click on “Add.”
3. In the next pop-up window, enter a new profile name.
4. Then you need to set up your existing email account again.
5. Restart Outlook (if it is open).

In Windows 10, you can press the Win key and type “Control.” You can then click on the “Control Panel” desktop app.

New Outlook Data File

If the cause of error 0x8004010F is a corrupted Outlook data file, then creating a new profile will fix it. To find the current location of your default Outlook data file, you can see the following path.

drive:\Users\\AppData\Local\Microsoft\Outlook
drive:\Documents and Settings\\Local Settings\Application Data\Microsoft\Outlook.

The above can be used to copy OST files to a new location.

1. Open Outlook. (The steps are mentioned for 2013).
2. File > Account Settings > Account Settings
3. Click on the “Data files” tab.
4. Select your OST file and note the file location.
5. Click on “Add.”
6. Give a new name

Make another Outlook Profile as default.

If you have multiple Outlook profiles, and if you get this error code, you change to another profile.

Generally, only one profile is required. But if problems persist, create a new profile as mentioned above. Then switch to the new profile as mentioned below.
1. Control Panel > Mail
2. On the next pop-up window, click on “Show Profiles.”
3. At the bottom, select the option that says “Always use this profile.”
4. In the drop-box, select your newly created profile.
5. When you restart Outlook, your email will be configured again.

Otherwise, you can import the PST or OST file into the current profile.
For that, follow these steps.
1. Start Outlook
2. File > Open & Export
3. Double-click on “Open Outlook Data File.”
4. Browse to the OST file location and select it.
5. It will be imported.

This way, if there are many emails and other items to be synced with the new profile, time can be saved.

Delete Multiple Outlook Data Files

When you add different email accounts to the same profile, multiple OST or PST files are created. If any of them are corrupted, the error code 0x8004010F is also shown.

Before deleting the corrupt OST file, set another file as the default data file. Then delete it. You can add the email account again or repair the OST file.

Change Outlook Profile location and Revert Back

If the location of the Outlook profile is also infected with a virus, there can be corruption in your data files. Otherwise, Outlook may not recognize the path properly.

In that case, temporarily change the file location of your profile and data files and then change back to the normal location again.

In MS Outlook 2013, follow these steps.

• Open Outlook.
• File > Account Settings > Account Settings
• On the Data Files tab, select your account and click on “Settings.”
  Note: You can note the present OST file location for future use.
• On the Advanced tab, uncheck the Use Cached Exchange Mode check box; click OK. Click OK.
• Then follow the above step and click on “Outlook Data File Settings.”
• Then browse to the new folder location of the OST file.
  Note. First, copy the old OST file to this new location.
• Now go to the “Advanced” tab once again. Check the “Use Cached Exchange Mode” checkbox. Click OK, OK.
• Now close all the open dialogue boxes and click OK.

Conclusion

There is no need to move your OST files to another computer. There is no need to take a backup also if you are using an Exchange server. But if there is a disaster with the server, it is important you take a backup.

You can also convert OST to PST files using third-party tools. This will help in using the data file in older versions of Outlook. You can then use it for offline purposes also.

To recover data from an OST file, you may need to convert it to a PST file. Then repair it and use it again. By following the above methods, you can fix the error code 0x8004010F easily.
