Why do PST password issues arise?

Let's say you copied your Outlook PST file from your old system to a pen drive & installed it on your new system.

Now, when you open Microsoft Outlook, it asks for your password, but:

  • The password is too old
  • Someone else set up the account
  • You simply trusted "Save Password"

In this situation, you have the email data, but you can't open it.

Be sure to check these simple things first

Before using a password recovery tool, try a few basic things:

Is Caps Lock on?
Have you tried a common password used in your old system?
Recreated your Outlook profile and attached the PST file?

If all of this fails, you'll need to proceed further.

Method 1: Recovery from a backup (if available)

If you have:

The old system is still running
Or have a backup of the PST without a password

Simply import that PST into the new system.
This is the safest & easiest method.

Example:
Opening Outlook on the old laptop → Export PST → Import to the new computer
