Create external contacts

In this step (and the next one), you have to use Windows PowerShell. To connect PowerShell to your Exchange Online organization.

After you connect PowerShell to your cloud-based organization, run the following command to create the external contacts:

Import-Csv .\ExternalContacts.csv|%{New-MailContact -Name $_.Name -DisplayName $_.Name -ExternalEmailAddress $_.ExternalEmailAddress -FirstName $_.FirstName -LastName $_.LastName}

Note: This command assumes that you are in the desktop directory in PowerShell. For example, C:\Users\Administrator\desktop.

To view the new external contacts, in the Exchange Control Panel, click Users & Groups > External Contacts > Refresh. They also appear in the shared address book in Outlook and Outlook Web App.
