How to Upload and Import Contacts in Outlook
Managing your contacts efficiently is a key part of staying productive in both personal and professional communication. If you are moving from another email platform, switching computers, or consolidating contact lists, knowing how to import contacts into Microsoft Outlook is an essential skill. Outlook makes this process simple with built-in tools that support various file formats such as CSV, PST, and vCard (VCF).
This comprehensive guide explains step-by-step how to import contacts into Microsoft Outlook across different versions, including Outlook for Microsoft 365, Outlook 2021/2019/2016, and Outlook on the web.
Understanding Contact Importing in Outlook
When you import contacts, you’re essentially transferring address book data—names, email addresses, phone numbers, company details, and more—from another source into Outlook’s Contacts folder. Outlook allows imports from:
-
A CSV (Comma Separated Values) file exported from another email program or service.
-
A PST (Outlook Data File) from another Outlook account.
-
A vCard (VCF) file containing contact information from mobile devices or other applications.
Importing these files ensures that your contact list is organized, searchable, and easily accessible across Outlook on all your devices.
Preparing Your Contacts File
Before importing, it’s crucial to have your contact data properly formatted and ready.
Step 1: Export Contacts from Your Previous Source
If you’re coming from Gmail, Yahoo Mail, Apple Contacts, or another Outlook account, export your contacts in one of the supported formats.
For most email providers, the CSV format is the most compatible option.
-
In Gmail: Go to Google Contacts → Export → Select CSV (for Outlook).
-
In Apple Contacts: Choose File → Export → Export vCard.
-
From another Outlook account: Export contacts to a .PST file.
Step 2: Review and Clean the File
Open your CSV file using Excel or another spreadsheet program to make sure:
-
Each column has clear labels (e.g., First Name, Last Name, Email Address).
-
Duplicate entries are removed.
-
Empty rows are deleted.
-
Data is properly aligned under the correct headings.
This helps avoid confusion when Outlook maps your data fields during import.
