Outlook Error 0x8004010F: Outlook Data File Cannot be Accessed

The official article in MS Knowledge Base (2659085) recommends to create a new Outlook profile in this case. However, this solution is not always applicable, especially if several mailboxes are connected to this Outlook configuration. (You will have to connect all mailboxes again and remember passwords for them)

Fortunately, there is an easier solution that involves creating a temporary PST file and switch mail delivery to it, and then the previous pst file has to be returned. This method is applicable both for Outlook 2010 / 2013 and Outlook 2016 / 365. Now let’s consider it in detail.

Note. This solution won’t help to resolve the issue if you are using an Outlook profile connected to the Exchange mail server over MAPI/ MAPI over HTTP.

  • Open the account settings window by clicking File-> Account Settings -> Account Settings outlook 2016 account settings
  • Select an e-mail account and click Change Folder outlook change pst file folder
  • Create a new temporary Outlook data file (New Outlook Data File) and create any folder in it. (In my case, Inbox folder has been created automatically.) Select this folder and click OKnew email delivery location
  • Now, as the message delivery folder, Outlook uses the folder you just created. Now you have to switch to original Inbox folder in the original pst file. You can do it in the same way using Change Folder buttonchange inbox folder in outlook
  • Close the account settings and click Send/Receive. The error 0x8004010F should disappear.

Tip. Don’t forget to delete the temporary PST file from your disk manually, since it is not deleted from the disk after you have deleted this PST file from your Outlook configuration.

If the method described above did not help, check the PST file permissions. If there are no problems, you will have to create the profile again and connect old PST files back.
