.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 #> Function Get-NormalizedDN { [cmdletbinding()] Param ( [Parameter(Mandatory = $true)] [string]$globalCatalogServer, [Parameter(Mandatory = $true)] [string]$groupSMTPAddress, [Parameter(Mandatory = $true)] [string]$DN, [Parameter(Mandatory = $true)] [string]$CN, [Parameter(Mandatory = $TRUE)] $adCredential, [Parameter(Mandatory = $TRUE)] [string]$originalGroupDN, [Parameter(Mandatory = $false)] [boolean]$isMember=$FALSE, [Parameter(Mandatory = $true)] [string]$activeDirectoryAttribute, [Parameter(Mandatory = $true)] [string]$activeDirectoryAttributeCommon ) #Output all parameters bound or unbound and their associated values. write-functionParameters -keyArray $MyInvocation.MyCommand.Parameters.Keys -parameterArray $PSBoundParameters -variableArray (Get-Variable -Scope Local -ErrorAction Ignore) #Declare function variables. $functionTest=$NULL #Holds the return information for the group query. $functionObject=$NULL #This is used to hold the object that will be returned.
