Get-NormalizedDN.ps1

<#
    .SYNOPSIS

    This function is used to normalize the DN information of users on premises to SMTP addresses utilized in Office 365.

    .DESCRIPTION

    This function is used to normalize the DN information of users on premises to SMTP addresses utilized in Office 365.

    .PARAMETER GlobalCatalog

    The global catalog to make the query against.

    .PARAMETER DN

    The DN of the object to pass to normalize.

    .PARAMETER CN

    THe canonical name of an object to normalize.

    .PARAMETER adCredential

    The AD credential for global catalog connections.

    .PARAMETER originalGroupDN

    The DN of the original group on premises.

    .PARAMETER isMember

    Boolean if the object to be tested is a member.

    .OUTPUTS

    Selects the mail address of the user by DN and returns the mail address.

    .EXAMPLE

    get-normalizedDN -globalCatalog GC -DN DN -adCredential CRED -isMember FALSE
