When you export your contacts from Outlook, a copy of your contacts is saved to a CSV file or other file type. You can then use this file to import your contacts to another email account.
In Outlook, you can export your contacts to a Comma Separated Values (.csv) file to move them to another email program.
At the top of your Outlook ribbon, choose File.
If your ribbon doesn’t have a File option in the top left corner, you’re using an older Outlook version. See what version of Outlook I have? to get to the import instructions for your version of Outlook.
Replace duplicates with items imported If a contact is already in Outlook and your contacts file, Outlook discards the info it has for that contact and uses the info from your contacts file. You should choose this option if the contact info in your contacts file is more complete or more current than the contact info in Outlook.
Allow duplicates to be created If a contact is in Outlook and your contacts file, Outlook creates duplicate contacts, one with the original Outlook info and one with the info imported from your contacts file. 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 your contacts file, Outlook keeps the info it has for that contact and discards the info from your contacts file. You should choose this option if the contact info in Outlook is more complete or more current than the info in your contacts file.
Outlook begins importing your contacts immediately. You’ll know it’s finished when the Import Progress box closes.
To see your contacts, at the bottom of Outlook, choose the People icon.
