There’s an ongoing debate about whether passwords should never expire or require regular changes for better security. While Microsoft leans towards eliminating password expiration, many organizations still enforce it as part of their security policy.
However, Microsoft doesn’t provide a native way to notify users before their passwords expire. Without timely reminders, users often get locked out, leading to increased help desk calls and reduced productivity.
To address this, I previously shared a Power Automate method, but many admins prefer PowerShell for automation. So, here’s a PowerShell script that sends password expiry notifications to users whose passwords are about to expire. Simply specify the number of days before expiration when running the script, and affected users will receive an email reminder.

PowerShell Script Example:
<h1>Define the number of days before password expiry to send notifications</h1>
$daysBeforeExpiry = 7
<h1>Get users whose passwords are about to expire</h1>
$users = Get-MsolUser | Where-Object { $<em>.PasswordNeverExpires -eq $false -and $</em>.LastPasswordChangeTimestamp -le (Get-Date).AddDays(-(90 - $daysBeforeExpiry)) }
<h1>Loop through each user and send notification</h1>
foreach ($user in $users) {
$emailBody = @"
Dear $($user.DisplayName),
Your password will expire in $daysBeforeExpiry days. Please change your password to avoid being locked out of your account.
Best regards,
IT Support
"@
Send-MailMessage -To $user.UserPrincipalName -Subject "Password Expiry Notification" -Body $emailBody -From "[email protected]" -SmtpServer "smtp.yourdomain.com"
}
What Undercode Say:
In the realm of cybersecurity, managing password policies effectively is crucial for maintaining organizational security. While Microsoft 365 offers robust tools for user management, the absence of native password expiry notifications can lead to operational inefficiencies. This PowerShell script bridges that gap by automating the notification process, ensuring users are reminded to update their passwords before expiration.
For administrators, mastering PowerShell is essential for automating repetitive tasks and enhancing system security. The script provided here leverages the `Get-MsolUser` cmdlet to identify users with expiring passwords and the `Send-MailMessage` cmdlet to dispatch notifications. This approach not only reduces the burden on help desks but also empowers users to take proactive steps in managing their credentials.
Beyond password management, PowerShell is a versatile tool for various IT tasks. For instance, you can use it to automate user provisioning, monitor system health, and enforce security policies. Here are a few additional commands to expand your PowerShell repertoire:
- Check Last Logon Time:
Get-ADUser -Filter {Enabled -eq $true} -Properties LastLogonDate | Select-Object Name, LastLogonDate -
Export User List to CSV:
Get-MsolUser | Select-Object DisplayName, UserPrincipalName, LastPasswordChangeTimestamp | Export-Csv -Path "C:\UserList.csv" -NoTypeInformation
-
Force Password Change at Next Logon:
Set-MsolUserPassword -UserPrincipalName "[email protected]" -ForceChangePassword $true
-
Monitor Azure AD Sign-Ins:
Get-AzureADAuditSignInLogs -Filter "createdDateTime gt 2023-10-01" | Select-Object UserDisplayName, AppDisplayName, CreatedDateTime

By integrating these tools and techniques, IT administrators can streamline operations, enhance security, and provide a better user experience. Automation, when done right, not only saves time but also reduces the risk of human error, making it an indispensable part of modern IT management.
