Import Contacts from PST and Enable Mobile Sync

This method uses the Outlook Import/Export wizard to restore your contacts to the desktop app, which then pushes them to your mobile device via account synchronization.

By importing your local PST backup directly into your active email profile on your desktop, Microsoft's server sync will automatically transfer the data to your connected mobile app.

1
Open the Import/Export Wizard

Launch Outlook on your desktop. Go to the 'File' tab in the top left corner, click on 'Open & Export', and then select the 'Import/Export' button.

2
Select the PST File Type

In the wizard window, choose 'Import from another program or file' and click 'Next'. Then select 'Outlook Data File (.pst)' and proceed.

3
Browse and Import to Contacts

Click 'Browse' to locate your saved PST backup file. Choose the option to import items into your current 'Contacts' folder and click 'Finish' to complete the local import.

4
Enable Mobile Synchronization

Once the import finishes, open the Outlook mobile app on your new phone. Go to 'Settings', tap on your specific email account, and toggle on 'Sync Contacts' to display them on your device.

Frequently Asked Questions

Where is my Outlook PST backup file located on my computer?

By default, modern versions of Outlook save PST files in the 'Documents\Outlook Files' folder. If you are using an older version of Windows or Outlook, they might be located in the 'AppData\Local\Microsoft\Outlook' directory.

Can I import a PST file directly into the Outlook mobile app?

No, PST files are designed exclusively for the Outlook desktop application. You must import the file on your computer first, and then allow the contacts to sync to your mobile device via your connected email account.

Why are my imported contacts not syncing to my new phone?

If contacts aren't syncing, verify that your Outlook mobile app is signed in with the exact same Exchange or Outlook.com account you imported the PST into. Additionally, ensure the 'Sync Contacts' toggle is enabled within your mobile app's account settings.
