Six Repair Methods to Fix Outlook Error 0x80004001

Before you start: Make a copy of the PST file you are about to work on. Never operate directly on the only copy. Let’s explore all the methods one by one:

Method 01: Check the Location of the PST File

If the PST is on a network share, external disk, or removable drive, Outlook can struggle to access it. How to check & fix:

1. Firstly, open Outlook and click File.
2. Then, choose Account Settings → Account Settings.
3. Now, go to the Data Files tab and note the PST file path.
4. If it points to a network path or external location, copy the PST to a local folder (for example, C:\Users\<yourname>\Documents\Outlook Files\).
5. In Outlook, remove the network-located file (after making a backup) and add the local copy.
6. In the end, also check the mapped drives with net use in the Command Prompt if mappings are involved.

Method 02: Turn Off Antivirus Protection (Temporarily)

1. First, temporarily disable real-time scanning in your antivirus and try the import.
2. If the import succeeds, add Outlook and the PST folder to the antivirus/f firewall exclusions.
3. Lastly, re-enable all security software after testing.

Method 03:Run Outlook in Safe Mode to Fix Outlook Error 0x80004001

Safe Mode disables add-ins and customizations that can interfere with normal operations. Steps to run in Safe Mode:

1. Primarily, press Windows + R.
2. Then, type outlook.exe /safe and press Enter.
3. Try importing the PST while Outlook is in Safe Mode.
4. If it works, disable problematic add-ins: File → Options → Add-ins → COM Add-ins → Go, then uncheck suspicious items and restart Outlook normally.

Method 04: Check the Account Settings of Outlook

Incorrect account settings may prevent Outlook from connecting or completing import tasks. How to verify:

1. Go to File → Account Settings → Account Settings → Email.
2. Select your account and click ‘Repair‘ or ‘Remove and Re-add‘ to re-enter the account with the correct credentials.
3. Finally, after fixing the account, try the PST import again.
