Before you can import contacts to Outlook, you'll need to...

1. Export your contacts from the current source (such as another email account or a contact management system) in a compatible file format, such as CSV or vCard.

2. Save the exported file to a location on your computer where you can easily access it.

3. Open Outlook and go to the Contacts section.

4. Click on the "File" tab in the top left corner of the screen.

5. Select "Open & Export" and then choose "Import/Export" from the dropdown menu.

6. In the Import and Export Wizard, select "Import from another program or file" and click "Next."

7. Choose the file type that you exported your contacts as (such as CSV or vCard) and click "Next."

8. Browse to the location where you saved the exported file and select it.

9. Choose how you want Outlook to handle duplicates (such as replacing, allowing duplicates, or not importing duplicates) and click "Next."

10. Select the destination folder in Outlook where you want to import the contacts (such as your main Contacts folder) and click "Next."

11. Click "Finish" to complete the import process. Outlook will import the contacts from the file you selected into your Contacts folder.
