Cannot bind argument to parameter 'UserPrincipalName' because it is null

What am I doing wrong here?  I have a txt file that looks similar to this:

******@companyname.com

Hi Brian,

Thanks for your information in Private Message.

The files you provided have correct formats.

According to my test, I am able to remove licenses from a csv file using following scripts:

1.

connect-msolservice

(Sign in with your administrator account)

2.

Import-Csv "<your csv file path>" | ForEach-Object {

    $User = Get-MsolUser -UserPrincipalName $_.UserPrincipalName

    Set-MsolUserLicense -UserPrincipalName $User.UserPrincipalName -RemoveLicenses <your domain>:VISIOCLIENT

}

(Change the CSV file path and the domain name and copy the scripts to powershell then press enter)

3.

To check the result, please sign in Office 365 portal and check one user if his visio license is removed in "Active users".

In addition, if there are any error messages when you run the scripts, please capture the screenshots to share with me and I will provide further help for you.

Best Regards,

Gloria

Answer 3

What I'm trying to do is simply remove an O365 (Visio) license from all users that are assigned one.

Hi Brian,

Here are some articles for your reference: 

Set-MsolUserPrincipalName

Add User Principal Names in Active Directory via PowerShell.

I would like to confirm some information with you for further troubleshooting:

1. Do you want to rename a user account or update user details with a text file?

If not, could you please list your steps which caused the issue to share with us?

2. In addition, can you be more descriptive of what it is that you want?

Best Regards,

Gloria
