Powershell help - get a recursive list of user created inbox subfolders based on variable

Question

I have a requirement to identify all user mailboxes that have user created subfolders under the Inbox folder.  I can use the following powershell command to obtain the information I need, but only for one user at a time:
Get-mailboxfolderstatistics username -FolderScope Inbox | select name, foldertype | Where-Object {$_.FolderType-eq "User Created"}
I have a list of about 700 usernames which can be loaded into a variable.  I've tried experiementing with the ForEach-Object cmdlet but I can't seem to get it to work.  Is there a way to get my command above to loop through all usernames stored in
a variable, and then export to CSV?

For all users dynamically...
get-mailbox | Get-mailboxfolderstatistics -FolderScope Inbox | Where-Object {$_.FolderType -eq "User Created"} | Select Identity, Name, FolderType | Export-CSV Mailbox-Folder.csv -NoTypeInformation
From a variable...
$mailboxes = get-mailbox . .. . . 
$mailboxes | Get-mailboxfolderstatistics -FolderScope Inbox | Where-Object {$_.FolderType -eq "User Created"} | Select Identity, Name, FolderType | Export-CSV Mailbox-Folder.csv -NoTypeInformation
