Outlook 2010 - Importing Contacts / Address Book(s)

This document provides an overview of how to import contacts/address books from other email accounts into your Office 365 account if using Outlook 2010.

Important: If you use Outlook Web App and Outlook 2013, 2011, or 2010, to connect to your Office 365 account, you will only need to import these contacts once using any of these clients. Once imported, they will be available to you in the other clients.

How do I import contacts using Outlook 2010?

  1. Export the contacts from your other email account to a .csv file. Instructions for exporting your contacts from a variety of email clients are available here. Note where you save the .csv file.
  2. Start Outlook.
  3. Click the File tab.
  4. Click Open.
  5. Click Import.
  6. Click Import from another program or file, and then click Next.
  7. Under Select the file type to import, click Comma separated values, and then click Next.

The most common is Comma Separated Values (Windows), also known as a CSV file. If you are importing contacts that were exported from Outlook to an Outlook Data File (.pst), click Outlook Data File (.pst).

  1. Under File to import, click Browse, select the file that you want to import, and then click OK.
  2. In the Import a File dialog box, under Options, click one of the following:
    • Replace duplicates with items imported    If an Outlook contact already exists, it is replaced by the information that you are importing.
    • Allow duplicates to be created    If an Outlook contact exists, the imported contact is created as a second contact.
    • Do not import duplicate items    If an Outlook contact exists, the information for the imported contact is not imported.
  3. Click Next.
  4. In the Import a File dialog box, under Select destination folder, click a folder for the imported contacts, and then click Next.

This usually is the Contacts folder unless you have multiple accounts, or have created multiple contact folders for an account.

  1. If your contacts were exported from Outlook, click Finish. If they were exported from another client, like Thunderbird, see the instructions below:
  • Map Custom Fields
    • Before clicking Finish, select Map Custom Fields...

You will now see a screen similar to the image below. The "Values" column on the left side displays the items that you are importing. The right side has two columns. The "Field" column represents fields in your Outlook address book, and the "Mapped from" column shows which data will fill each field. For example, if the field E-mail 1 is mapped from the value Business E-mail, your contact's business email address will show up in the first email address field once it's imported to Outlook.

To make sure your contacts import correctly, make sure that the items in the "Mapped from" column are consistent with items in the "Field" Column. You will have to click on the plus sign () icons to expand items in the "Field" column. To designate a field for a given value, simply drag the item from the "Value" column to the "Field" column.

In the example below, The name fields do not have anything in the "Mapped from" column. If these contacts were imported as is, none of the contacts would have names in the Outlook address book.

After dragging the values Title, First Name, Middle Name, and Last Name to the right hand side, the names will import correctly. This process should be repeated for email addresses, and any other piece of contact information that you want imported.
