Outlook reports a data file access error for two reasons Microsoft lists. Someone moved the PST file to another disk location or the Outlook profile is corrupted. POP accounts need a temporary file. IMAP accounts need removal and a new setup with the same address. Check the account type first.
Send and receive stops and Outlook shows a data file access error. Microsoft ties the message to two causes.
Steps follow the Microsoft Support page on the Outlook data file cannot be accessed error.
What Causes the Data File Error?
- Moved PST file. Your PST file sits in a different disk location than before.
- Corrupted profile. Your Outlook profile is damaged.
How to Find Your Account Type?
Open File, Account Settings and Email. Check the Type column for the account that shows the error. Your fix depends on whether the account is POP/SMTP or IMAP.
How to Fix a POP Account?
- Create a temporary data file.
- Set the Inbox of the temporary file as the new mail delivery location.
- Set delivery back to the Inbox of your real data file.
- Try Send/Receive again.
How to Fix an IMAP Account?
- Remove the account.
- Add it again with the same email address and password.
- Try Send/Receive again.
Microsoft states messages remain on the server for IMAP accounts. Removal does not delete mail.
What if the Error Remains?
Microsoft points to a second article, KB 813514, for other solutions. Microsoft does not list error code 0x8004010F or steps for a new profile or a repair tool. See how to use Scanpst.exe when you suspect a damaged PST file.
