If you have an old pst or an old archive pst and you want to view your old email, you can open it in your Outlook profile.
Do not use File, Import and Export menu, especially if it's an Archive pst – you may end up with duplicates and will not be able to remove them using Autoarchive (because archive uses the modified date and importing changes the modified date). Just open it in Outlook.
To open a *.pst while Outlook is running:
In all versions of Outlook: go to File, Open, Outlook Data File menu and browse to find the personal folders data file (pst) you want to open.
To add an existing personal data file to your profile:
The steps to open an existing data file in your profile are similar in all versions of Outlook but the dialogs are different.
In all versions:
- Open Control Panel and find the Mail applet. If you use the Category view in Windows XP, Windows 7 or 8′s Control Panel, look for the Mail applet in the User Accounts category.
- Select the Show Profiles button. If you only have one profile, you can click the Data Files button.
- Select your profile and click Properties
Continue the steps for your version of Outlook below.
Outlook 2007 and up
To add a pst file to your profile, click the Add button and select the data file you want to add. In some versions, a dialog will ask what type of data file (Outlook data file or Outlook 97-2002 data file), just click Ok to move to the Open file dialog.
Select the pst file you want to use as your default for delivery and click Set as Default.
Outlook 2003 and older
If you just created your profile and have the Profile dialog open, skip to Step 2 after clicking Finish in the profile wizard.
- Select Email Accounts then View or change email accounts.
- Select New Outlook data file and find your existing PST, add it to the profile and set it as the default.
- Ok your way back to the Email Accounts dialog and select the PST you just added in the Deliver new e-mail to the following location field. The pst file that is visible in this field is the one Outlook will use as your default pst file.
- When you return to the Mail Setup dialog, choose Data Files and remove the extra personal folders from your profile.
- While the New dialog looks like you can only use it to create a new pst, you can select an existing pst file to open.
To remove a data file from Outlook when you are finished using it:
Right click on the top level and choose Close.
Note: You can have several pst's in your profile and only need to close a pst file if you prefer to keep the folder list less cluttered or need to move the file.
