After recreating the profile, Outlook now keeps asking for a password for the same PST file, but I am 100% sure that I never set any password on it. Because of this, I am unable to open my mailbox data and access important emails. Has anyone experienced a similar PST password problem after Outlook profile corruption? I am looking for a simple, safe, and quick solution to unlock or remove the PST password without damaging the data.
This is a known edge case with Microsoft Outlook after profile corruption, PST files can sometimes behave as if they’re password-protected even when no password was ever set. It’s usually not a real password issue, but corruption in the PST header or profile linkage.
A quick thing to try first is Outlook’s built-in repair tool (SCANPST.exe). It can fix minor corruption and sometimes clears this false password prompt. You’ll find it in your Office installation folder—run it against the PST and let it repair any errors.
If that doesn’t work, the safest approach is to use a reliable PST repair/unlock tool like Remo Repair Outlook PST, which is designed to handle corrupted PST structures and remove such access issues without altering your data. These tools rebuild the file internally rather than forcing access, so the risk of data loss is minimal.
Avoid random “free password cracker” tools—they can further corrupt the file. This is most likely PST corruption, not an actual password—repairing the file should restore access.
