Import-MailContactsFromCSV.ps1 is a PowerShell script to automate the creation of Exchange mail contacts using a CSV file for input.
The current version of the script supports a CSV file containing the following fields, which are the minimum details required for creating a mail contact in Exchange:
- Name
- ExternalEmailAddress
The script looks for a file named Contacts.csv by default, or you can use the optional -CSVFileName parameter to specify your own file name. You can also set a default OU for contacts in the script, or use the -OU parameter to specify an OU.
Download the script from the TechNet Gallery or GitHub.
Example usage:
C:ScriptsImportContacts>.Import-MailContactsFromCSV.ps1 C:ScriptsImportContacts>.Import-MailContactsFromCSV.ps1 -CSVFileName externalcontractors.csv C:ScriptsImportContacts>.Import-MailContactsFromCSV.ps1 -OU "exchangeserverpro.net/Company/Contacts"
If you are providing this script to a non-administrator to use, you can configure an RBAC custom role to limit their permissions to only allow them to create contacts in a specific OU, as demonstrated here.
This was extremely helpful after a migration to Google, where contacts needed to be created for all users in the new google domain to enable forwarding.
Thanks a lot!! Saved me possibly a few hours or coding / testing something similar.
This blog was… how do you say it? Relevant!! Finally I’ve found something which helped me.
Thank you!

The term ‘Import-MailContactsFromCSV.ps1’ is not recognized as the name of a cmdlet, function, script file, or operable
Make sure you dot source the script, if you’re in the correct directory, you still need to preface the filename with “./”. Powershell will do this for you if you use the tab completion feature by typing some of the filename and then the tab key, e.g. “Update-MailCo” .
I tried code:
Import-Csv .\ExternalContacts.csv|%{New-MailContact -Name $_.Name -DisplayName $_.Name -ExternalEmailAddress $_.ExternalEmailAddress -FirstName $_.FirstName -LastName $_.LastName}
I get this error:
The external e-mail address joseph.smith@verizonwireless.com is not an SMTP e-mail address.

what does it mean it is not an SMTP email address?
very novice on powershell… just trying to upload our csv file of contacts into exchange admin users…
thank you
Make sure there is no blank space after the email address preceding the 1st comma in each record.
I had the same error that I didn’t see when opening the CSV file in excel but it was evident when using notepad. Once this space was removed it worked.
@Paul: you have forgotten to write exactly how the .csv should be written.
I had to reverse engineer your code in order to understand that.
the file should be like this
Name,ExternalEmailAddress
john,john@example.com
I keep getting an OU related error.
Command I use:
Import-MailContactsFromCSV.ps1 -CSVF
ileName C:\IT\importimport.csv -OU “domain.org/MyBusiness/Users/TargetOU”
The OU domain.org/MyBusiness/Users/TargetOU was not found

@CaZzzle you must run the script in the Exchange Powershell
