Outlook PST Password Remover software works on the .pst files you already own. Point it at an Outlook data file you can no longer open because the password slipped your mind, and it either brings back a working password or strips the password off the file, whichever you prefer. The reason it is this fast is worth knowing. A native .pst password is not the key that encrypts your mail. It is a small 32-bit checksum Outlook keeps inside the file and compares whenever you type the password. The app reads the mailbox directly and reverses that checksum, so recovery on a native .pst is close to instant and works nearly every time. Add one file or a whole folder, press Start, and save the result on your own PC.

How to remove or recover a PST password

Add your .pst files.

1. Add your .pst files

1. Add your .pst files

Open the app and drag your locked Outlook data files into the window, or use Add Files or Add Folder. You can queue a single .pst or a whole batch of old archives in one go.

Press Start.

2. Press Start

2. Press Start

Click Start and let the app read each file. It works out a password that opens the archive and can also clear the password from the .pst, so the file opens with no prompt next time. Progress shows as it goes.

Preview and save.

When it finishes, the app shows the mailbox in a preview window so you can confirm you have the right file. Pick a folder and save the password-free .pst, or note the recovered password.

Built for your own Outlook archives

Get back into an archive you were shut out of.

Get back into an archive you were shut out of

The classic case is an old .pst you set aside years ago, say a backup from PC you are about to retire, or a mailbox a colleague left behind, and the password is long gone. Outlook itself gives you nothing here: its own Change Password box only helps while you still know the password. It reads the archive anyway and hands the mail back. A decade of messages does not get thrown out with the old machine.

No overnight guessing, no gamble

With a PDF or a ZIP you depend on the encryption, and a strong one can stay shut for good. A native .pst works differently. Since the password is only a checksum and not the thing that scrambles your mail, there is no long computation to run. The result comes back in about a second and succeeds on close to every native file. You are not paying for a maybe.

Your mailbox never leaves your computer

A .pst holds years of private correspondence, and the last thing it needs is a trip through some stranger's upload form. Everything here runs on your own Windows PC. The file is opened, read, and saved locally, and no copy is sent anywhere.

Recover a forgotten open password

Lost the password that opens an Outlook data file? The app reads the store and returns a working password for it, You can then type it into Outlook and open the archive the usual way.

Remove the password from the file

Prefer to be rid of the prompt for good? The app strips the password out of the .pst and saves a clean copy that opens with no password at all. That is handy before you import an old archive into a fresh Outlook profile.

One Start button, both jobs

You do not have to decide up front. Start recovers a working password and can clear the protection in the same pass, and you keep whichever result you need.

Clear a stack of archives at once

Point it at a stack of retired archives, a shared drive full of old .pst files, and process them in one batch instead of opening and saving each one by hand.

Handles ANSI and Unicode .pst

It reads both the older ANSI .pst that Outlook 97 to 2002 created and the Unicode .pst from Outlook 2003 and later, so an ancient archive is as recoverable as recent one.

See the result before you buy

The trial does the full job and opens the recovered mailbox in a preview window, so you can confirm it worked on your file. The full version saves the password-free .pst and shows the complete password.

Who it is for

People with an old personal archive

Reopen a .pst you protected long ago and can no longer recall the password for, like old mail from a laptop you have since replaced, or a family archive you saved and then locked.

IT and help desk staff

Consolidate or migrate retired .pst files across a team, where the person who set each password left long ago, without raising ticket for every mailbox.

Consultants and anyone who inherited a mailbox

Open a data file that came with the job, a predecessor's archive you are authorized to read but were never handed the password to.

What it can open, and what it cannot

A short, honest map of where this tool applies. It is about the .pst password, not any separate on-disk scrambling you may have switched on, and not your mail account password.

🙋 Frequently Asked Questions

Add the .pst to Outlook PST Password Remover and press Start. The app reads the Outlook data file directly, works out a password that opens it, and can also strip the password so the file opens with no prompt at all. On a native .pst this takes about a second, and you see the mailbox in a preview before you save anything.

It lives inside the .pst file itself, as a small value Outlook keeps in the file's properties (PidTagPstPassword). That value is a 32-bit checksum of the password, not the password text and not an encryption key. When you type a password, Outlook just checks it against that number, which is why a tool that reads the file directly can open it without the original password.

Usually yes, when the file is a native Outlook .pst and it is yours to open. The app does not rely on you remembering anything; it reads the archive and returns a working password or clears the lock. Old backups from a retired PC are the most common case, and the surest way to unlock PST files you own but forgot the password to.

Yes. Outlook's own Change Password option only works while you still know the current password, so it is no help once you have forgotten it. This tool goes straight to the file, so nothing needs resetting. You get a working password back, or a copy of the .pst with no password on it.

Age does not matter here. Whether the archive is from last year or from an Outlook version two decades old, the password is stored the same way. Point the app at the file and it opens, ANSI or Unicode alike.

No. Here is the part people get wrong. The password on a native .pst does not encrypt your mail. Microsoft's own file-format spec says the password is not used to secure the data at all; it is only a checksum Outlook compares. A .pst can carry a separate, optional on-disk scrambling, but that is not tied to the password. Because there is no real encryption standing in the way, honest recovery is quick, and we would rather tell you that plainly than oversell it.

A .pst is a standalone archive, and its password lives in the file; that is the one this tool handles. An .ost is only an offline mirror of a mailbox that stays on the server, so it has no password of its own and the file itself holds nothing to recover. If you are locked out of an .ost, the real lock is your account or your mail server, not the file.

Not always, and that is fine. Because the stored value is a 32-bit checksum, more than one password can match it. The app may hand you a password that is not the exact text you first set, yet it opens the file just the same. If you would rather skip passwords altogether, just remove it.

No. The app does not rebuild or re-import your mail. It changes only the password setting and leaves every folder, message, and attachment exactly where it was. It writes a copy you save, so your original file stays untouched until you are happy with the result.
