I am in need to iterate through a list of emails (that happen to be username in Sitecore CMS) and then remove the users. I would like to have an "if" statement to see if account is present before attempting to remove it.

# list of emails, one per line, ex. "[email protected]"
$removeEmails = Get-Content C:\AccountsToRemove.txt     
foreach ($email in $removeEmails) {
  $account = "Storefront\$($email)"
  if (Test-Account -Identity $account)
     $email | Remove-User
     Write-Output "Removed: '$email'"

But I get PowerShell complaining as follows:

Test-Account : Cannot bind parameter 'Identity'. Cannot convert value "Storefront\[email protected]" to type "Spe.Commands.Security.AccountIdentity". Error: "The name 'Storefront\[email protected]' is improperly formatted.

The name can only contain the following characters: a-z, 0-9, periods, dashes, underscores, backslashes, and spaces. Parameter name: name"

How do I overcome this issue?

Thank you for your help in advance!!


I found a thread mentioning that RegEx is too restrictive: Cannot add a User to a Role where the User name contains the "@" sign using PSE

Hopefully issue will be resolved in some next version. Still same issue in Sitecore PowerShell Extensions Windows PowerShell 5.1 (Sitecore 9.3)

BUT if anyone can think of a workaround... please help!! and no,

Get-User -Filter * | Where-Object {$_.Profile.Email -like "[email protected]"} | Remove-User

is not viable with over million users - Sitecore CM hangs like crazy. This is based of post here: https://munirhassan.com/2021/03/29/remove-sitecore-users-from-the-core-database/

NOTE 1 (sitecore domain)

Was able to add user with email as username after easing restrictions with:

<setting name="AccountNameValidation" value=".+" />

and running the script (user is in "sitecore" domain: "sitecore\[email protected]")

Remove user with email as username - sitecore domain

NOTE 2 (Storefront domain with plus)

Remove user with email as username - Storefront domain

NOTE 3 (Storefront domain no plus)

Remove user with email as username -Storefront domain no plus

  • Can you add this setting to allow user creation with email? and try example I posted. <setting name="AccountNameValidation" value=".+" /> Commented Jun 24, 2022 at 22:46

Working example from 9.3

    $removeEmails = @("[email protected]","[email protected]")
    foreach ($email in $removeEmails) {
        $account = "Storefront\$email"
        if (Test-Account -Identity $account)
           $account | Remove-User
           Write-Output "Removed: $account"
           Write-Output "Not found user: $account"
  • No, it does not work. Now "Storefront" part is lost.

  • And the issue is that it does not like the "@" in the username (this is being an email and all). I believe this is the issue. Thoughts?
