Hello @Nick Marchese
Thank you for reaching out. I would like to confirm that currently Azure AD Admin or Office 365 Admin Center do not support exporting Last Password Change Date Time details. However, you can use following PowerShell commands to export these details in CSV.
Connect-MsolService
Get-MsolUser -All | Select-Object UserPrincipalName,LastPasswordChangeTimestamp | Export-Csv -Path "C:\LastPasswordChangeTimestamp.csv" -NoTypeInformation
Above script will retrieve all users from Azure AD and select the UserPrincipalName and LastPasswordChangeTimestamp properties.
I hope this answer helps to resolve your issue.
