When moving or working with Outlook PST files you may experience the following error in Outlook:

1
“Sending reported error (0x8004010F): Outlook data file cannot be accessed.”

The following is a simple fix for this error. However, the error must be accompanied by a specific additional symptom: the folder list is missing when you highlight an email account.

To see if this fix applies to your situation, open “Mail” from your Control Panel. Then click “Email Accounts…” When your email account is highlighted, you should see a folder name and PST name next to the “Change folder” button at the bottom of the window. See the following illustration:

Note that when the email account is highlighted there is a folder and PST file listed at the bottom of the window. If you do not see this listed (if the space is empty), the following may fix your “0x8004010F” error.

  1. Click on the “Data Files” tab. Then click “New Outlook Data File…” (or “Add” depending on your Outlook version)
  2. The PST file you are creating is temporary, so you can give it any name and store it at any location.
  3. Once the temporary PST has been created, click back on the “Email” tab.
  4. Highlight the email account experiencing the 0x8004010F error and click “Change folder” at the bottom of the window.
  5. Click the plus to expand the name of the temporary PST file you created in step 2. Click “New Folder” on the right and give it a temporary name. Highlight this folder and click OK.
  6. You should now see the temporary folder and PST listed at the bottom of the window, but you aren’t quite done.
  7. Repeat steps 4 and 5, but choose your original PST file and original Inbox folder. After you click OK, you should see your original PST and original folder listed at the bottom of the window. If you have other accounts experiencing the problem, perform these same steps (you can use the same temporary PST/folder for all of them)
  8. Click OK and close all of the remaining windows. Open Outlook and perform a Send/Receive.

Again, this trick will only solve the 0x8004010F Outlook error if you do not see a PST/folder listed when viewing your email account(s). If this does not work for you, another (but more drastic) option would be to remove and re-create your Outlook profile (and re-use your existing PSTs).
