Company Archive PST Password Recovery the Proper IT Procedure
In an office, a locked archive PST is not a personal puzzle. It holds company mail, it belongs to the company, and opening it needs a documented process. Here is the procedure IT teams should follow every single time.

Watch the full video - the complete PST password recovery process shown live, step by step
The same recovery that is a harmless favour on your own file becomes something else entirely on a colleague's mailbox: access to years of company correspondence. The technique does not change - the process around it must. Permission, copies, logging and a clean handover are what separate professional IT work from a problem waiting to happen. Use every guide here only for PST files you own or are authorised to open - your own mailbox archive, or your company archives with documented permission. Recovering the password of someone else's mail file without permission is not a fix, it is unauthorised access.
IT recovery ticket (example)
Request: Accounts archive 2022 - password forgotten by the user
Approved by: Department manager - written approval on the ticket
Action: password recovered on a copy on the IT workstation, original untouched
Handover: user set a new password and saved it in the office vault
If it is not written in the ticket, it did not happen. That record protects the user, the company and you.

Step 1 - Get the Permission in Writing
Before touching the file, establish three things on the ticket: whose archive it is, the business reason it must be opened, and who approved it - the user themselves for their own live archive, or their manager or HR for a leaver's or a shared archive. A verbal "just open it" in the corridor is not approval for opening someone else's mailbox - even inside your own company, even for IT. Thirty seconds of writing now is the whole difference between a recovery and unauthorised access.

Step 2 - Work Only on a Copy, on an IT Machine
Copy the PST to the IT workstation. The original file is never the working file
Run the recovery there, using the route from the core guide on this page - tool scanned first, recovery against the copy
Never install recovery tools on the user's PC or on a server for this job; your own controlled machine only
Log the date, the tool used and the result in the ticket as you go
The recovered string you obtain is a skeleton key produced from a weak hash - treat it as sensitive from the moment it appears on screen. It does not go in the ticket, in email, or in chat.

Step 3 - Open, Verify, and Hand Over in Front of the User
Open the file with the recovered password and confirm the mail is intact - a few folders, a search, the date range the user expected. Then close the loop properly: the user sets a brand-new password themselves, on the spot, using the Change Password screen, and saves it in the company vault as the prevention pattern requires. Done right, you finish the job not knowing the working password to that archive - which is exactly where a professional should end up.

Step 4 - Close the Loop and Fix the Cause
Delete your working copy securely - it is a full copy of someone's mailbox
Update the archive register: file, owner, backup location, vault entry name
Record the prevention step in the ticket: password now stored in the vault
If this user has been here before, say so kindly and plainly: the register and vault entry are the fix. A third recovery is a process failure, not a password failure
Company mail, company rules: without documented approval, the identical mouse clicks stop being IT support and become unauthorised access - even for the IT person, even with good intentions.
Watch the Complete Process in the Video
The video shows the technical recovery; this page is the professional wrapper around it. Watch the video, then run the procedure.
The employee has left the company. Can IT open their archive PST
Only under company policy and written direction from management or HR, recorded in a ticket. The mail is company data, but the process still matters: approval first, work on a copy, access logged, and contents shared only with the approver.
Should IT keep a copy of the recovered password
No. The recovered value came from a weak hash and acts as a skeleton key. The user - or the archive's new owner - sets a fresh password at handover, and that one goes into the company vault only if policy requires escrow.
What if the archive belongs to a director who refuses the paperwork
The process protects them most of all. Ask politely, in writing. If they direct the work themselves as the data owner, record their written approval on the ticket and proceed exactly the same way - the steps do not shrink for seniority.
