    .SYNOPSIS
        Sends detailed reports on Azure Users, Groups, and Roles via email.

    .DESCRIPTION
        This PowerShell script generates a report on Azure subscription user roles, groups, and their memberships, and then emails this report as an attachment. It logs into Azure 
        using a managed identity, fetches role assignments for given subscriptions, compiles them into a report, and mails this report to specified recipients. The script uses 
        the .NET Mail API for secure email transmission.

    .PARAMETER EmailUsername
        The username used to authenticate with the SMTP server.

    .PARAMETER EmailPassword
        The secure password used for SMTP authentication.

    .PARAMETER From
        The email address from which the report will be sent.

    .PARAMETER To
        An array of recipient email addresses to whom the report will be sent.

    .PARAMETER Cc
        An array of CC recipient email addresses.

    .PARAMETER Subject
        The subject line of the email.

    .PARAMETER Body
        The body text of the email, describing the contents of the report. This can be either HTML or plain text.

    .PARAMETER SMTPServer
        The SMTP server used for sending the email.

    .PARAMETER SubscriptionIds
        Array of Azure subscription IDs to be included in the report.

    .PARAMETER WhatIf
        A switch to simulate the script execution for testing purposes without performing any actual operations.

    .EXAMPLE
        PS C:\> .\Get-AzRoleAssignmentReport.ps1 -EmailUsername '[email protected]' -EmailPassword (ConvertTo-SecureString 'Secure123' -AsPlainText -Force) -SMTPServer 'smtp.example.com' -From '[email protected]' -To '[email protected]','[email protected]' -Cc '[email protected]' -Subject 'Monthly Azure Report' -Body 'Attached is the monthly Azure usage report.' -SubscriptionIds 'sub1','sub2'

        Sends an email with an Azure roles report for specified subscriptions.

    .NOTES
        Ensure that proper Azure permissions are configured for accessing subscription details and role assignments. This script requires the Azure PowerShell module and an SMTP server that supports SSL.
