密码过期提醒是一种安全措施,用于确保用户定期更改其密码,以减少密码被盗用的风险。当用户密码过期时,系统发送提醒通知,告知需要更改密码。这种提醒通常可以以电子邮件、系统通知的方式发送给用户,提醒中通常包含有关如何更改密码的提示以及过期日期和时间等设置。
为了确保密码安全,建议用户定期更改密码,并使用密码策略来创建难以猜测的密码,同时还应该启用密码过期提醒功能,以便及时收到通知并采取必要的行动。
在本中,我们将演示如何创建Microsoft Graph PowerShell脚本,该脚本可在用户的Office 365密码即将过期时自动向用户发送电子邮件通知。
前提条件:安装Microsoft Graph PowerShell模块,命令为:
Install-Module Microsoft.Graph
使用此PowerShell脚本向密码即将过期的所有用户发送电子邮件提醒:
Connect-MgGraph -Scopes "User.Read.All", "Mail.Send"
$NotificationThreshold = 7
$PasswordExpiryThreshold = 90 #By default 90 days Password expiry
$AllUsers = Get-MgUser -All -Property Id, DisplayName, UserPrincipalName,Mail,UserType, AccountEnabled,PasswordPolicies,lastPasswordChangeDateTime
ForEach ($User in $AllUsers)
{
If (!$User.AccountEnabled -or $User.PasswordPolicies -contains "xDisablePasswordExpiration" -or $User.userType -eq "Guest") {
continue
}
$PasswordExpiryDate = $User.lastPasswordChangeDateTime.AddDays($PasswordExpiryThreshold)
$RemainingDays = ($PasswordExpiryDate - (Get-Date)).Days
If ($RemainingDays -le $NotificationThreshold) {
$EmailBody = "
Hello $($User.DisplayName),
<br/><br/>
Your Office 365 password will expire in $remainingDays days. Please change your password before it expires to avoid any disruption in accessing your account.
<br/><br/>
To change your password, follow these steps:<br/>
<ol>
<li>Sign in to Office 365 (https://www.office.com)</li>
<li>Click on your profile picture in the top right corner.</li>
<li>Select 'View account'.</li>
<li> Click 'Password'.</li>
<li> Follow the instructions to change your password.</li>
</ol>
<br/>
Thank you,<br/>

$MailParams = @{

说明:此脚本将提示输入登录凭据,并遍历组织中的所有用户,计算密码过期日期,并向密码将在指定阈值(在我们的情况下为7天)内过期的用户发送电子邮件通知。您可以修改$NotificationThreshold变量,以调整发送通知时密码过期前的天数。
