Outlook Error 0x8004010F


message: ' - Sending' reported error (0x8004010F) : 'Outlook data file cannot be accessed

If for some reason you move your outlook personal folder (PST) file inside windows explorer you may get the above error. In this instance I am a long time user of Outlook and to keep better organization of my files, I decided to move my legacy PST's in to the new path that Outlook expects them. I was getting tired of traversing the OS to the old paths every time I wanted to open an old PST or create a new one. Microsoft has decided to yet again change the location of where outlook keeps your email data files.
It use to be in C:\Documents and Settings\\Local Settings\Application Data\Microsoft\Outlook
With the change in operating systems it moved to C:\Users\\AppData\Local\Microsoft\Outlook
Now with Microsoft's newest release of Office PST's are kept C:\Users\\Documents\Outlook Files

After moving the PST Outlook asks for the new location as usual:


Traverse your folders to your new Outlook path and select the correct PST file.


Click OK on the next two prompts.



Launch Outlook again. Outlook will display a Send/Receive error in the red highlighted area. Click on the error message.


The Following Reported Error (0X8004041F) :'Outlook data file cannot be accessed.' will display.


Close the above window and return to Outlook's main window. Click on File tab then Account Settings buttons

Notice where around Change Folder button that there is no information around it.
It should be showing the folder path to your PST. Click Change Folder button


Click the ( + ) plus sign to expand the folder to your Inbox


Select your Inbox then click on New Folder Button


Call the folder temp and click OK


You should see the new temp subfolder highlighted in blue below. Click OK


Notice the folder path information now displayed by the Change Folder button. Click Close


Return to the main Outlook home window.
Press ( F9 ) on your keyboard to check for mail. The error should be gone.
Notice how the new email message landed in the temp folder. We will need to go back and change it back to Inbox.

Click on File tab then Account Settings buttons

Click Change Folder button


Select the Inbox highlighted in blue and click OK


Notice how the path is shorter listed next to the Change Folder button. Click Close


Be sure to move any emails that arrived in the temp folder are moved to the Inbox folder.
You may now delete the temp folder.


Now your email should work as it did before the (0X8004041F)error.
