Outlook PST Password Remover Software works with the .pst files you already own. Point it at an Outlook data file you can no longer open because you forgot the password, and it either recovers a working password or strips the password from the file. A native .pst password is a 32-bit checksum Outlook keeps inside the file and compares when 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

Open the Outlook PST Password Remover Software 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

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

Preview and save.

Preview and save

When it finishes, the app shows the mailbox in a preview window. 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

An old .pst may be a backup from a PC you are about to retire or a mailbox a colleague left behind, with the password long gone. Outlook's Change Password box only helps while you still know the password. Outlook PST Password Remover Software reads the archive anyway and hands the mail back. It can hold a decade of messages.

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. Its password is only a checksum, not the thing that scrambles your mail, so there is no long computation to run. The result comes back in about a second and succeeds on close to every native file.

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 type it into Outlook and open the archive as usual.

Remove the password from the file

The app strips the password out of the .pst and saves a clean copy that opens with no password. Use it before you import an old archive into a fresh Outlook profile.

One Start button, both jobs

Start recovers a working password and can clear the protection in the same pass. Keep whichever result you need.

Clear a stack of archives at once

Point it at a stack of retired archives or a shared drive full of old .pst files, and process them in one batch.

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 a recent one.

See the result before you buy

The trial does the full job and opens the recovered mailbox in a preview window. The full version saves the password-free .pst and shows the complete password.

Who needs Outlook PST Password Remover Tool

People with an old personal archive

Reopen a .pst you protected long ago and can no longer recall the password for. Old mail may carry a locked slide deck as an attachment, and PowerPoint password recovery gets that file open once the mailbox itself is unlocked.

IT and help desk staff

Consolidate or migrate retired .pst files across a team when the person who set each password left long ago, without raising a ticket for every mailbox. Once they are unlocked, clearing out duplicate emails in PST files left over from overlapping accounts is a natural next step.

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 given the password for.

What Outlook PST Password Remover Software can open, and what it cannot

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 strip the password so the file opens with no prompt. On a native .pst this takes about a second, and you see the mailbox in a preview before you save anything.

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

Usually, when the file is a native Outlook .pst and it is yours to open. The app reads the archive and returns a working password or clears the lock. Old backups from a retired PC are the most common case.

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 an Outlook version two decades old, the password is stored the same way. The app opens ANSI and Unicode files alike.

No. A native .pst password does not encrypt your mail. Microsoft's own file-format spec says the password is not used to secure the data; it is only a checksum Outlook compares. A .pst can carry separate, optional on-disk scrambling, but that is not tied to the password. Because there is no real encryption standing in the way, recovery is quick.

A .pst is a standalone archive, and its password lives in the file. 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.

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. You can remove the password instead.

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