Import contacts from Google Gmail to Outlook

These instructions assume you’ve already exported your contacts from Google to a .csv file. Now you’re ready to import them.

1. At the top of your Outlook 2013 or 2016 ribbon, choose File.
2. Choose Open & Export > Import/Export.
3. Choose Import from another program or file, and then choose Next.
4. Choose Comma Separated Values, and then choose Next.
5. In the Import a File box, browse to find the file you saved in step 7 of the previous procedure, and then double-click to select it.
6. 
7. Choose one of the following to specify how you want Outlook to handle duplicate contacts:
   • Replace duplicates with items imported   If a contact is in Outlook and Gmail, Outlook discards the info it has for that contact and uses the info from Gmail. You should choose this option if the contact info in Gmail is more complete or more current than the contact info in Outlook.
   • Allow duplicates to be created   If a contact is in Outlook and Gmail, Outlook creates duplicate contacts, one with the original Outlook info and one with the info imported from Gmail. You can combine info for those people later to eliminate duplicate contacts. This is the default option.
   • Do not import duplicate items    If a contact is in Outlook and Gmail, Outlook keeps the info it has for that contact and discards the info from Gmail. You should choose this option if the contact info in Outlook is more complete or more current than the contact info in Gmail.
8. Click Next.
9. In the Select a destination folder box, scroll to the top if needed and select the Contacts folder > Next.
10. Choose Finish.
11. 
12. Outlook imports your contacts.
13. To see your contacts, at the bottom of Outlook 2016, choose the People icon.
