Workaround 3. Copy the Messages
Perform these PowerShell commands to begin coping messages from the basic domain to any specific proxy addresses present in the CSV file:
# Script: showproxies.ps1
# Copies all accounts in Office 365 that contain/don’t contain a specific
# proxyaddress to a .CSV file (addresses.csv)
#
# Change the following variable to the proxy address string you want to find:
# $proxyaddr = “onmicrosoft.com”
################################################################################
$proxyaddr = “onmicrosoft.com”
# Create an object to hold the results
$addresses = @()
# Get every mailbox in the Exchange Organisation
$Mailboxes = Get-Mailbox -ResultSize Unlimited
# Loop through the mailboxes
ForEach ($mbx in $Mailboxes) {
# Loop through every address assigned to the mailbox
Foreach ($address in $mbx.EmailAddresses) {
# If it contains XXX, Record it
if ($address.ToString().ToLower().contains(“onmicrosoft.com”)) {
# This is an email address. Add it to the list
$obj = “” | Select-Object Alias,EmailAddress
$obj.Alias = $mbx.Alias
$obj.EmailAddress = $address.ToString() #.SubString(10)
$addresses += $obj
}
}
}
# Export the final object to a csv in the working directory
$addresses | Export-Csv addresses.csv -NoTypeInformation
# Open the csv with the default handler
Invoke-Item addresses.csv

param( $inputFile )
Function Usage
{
$strScriptFileName = ($MyInvocation.ScriptName).substring(($MyInvocation.ScriptName).lastindexofany(“\”) + 1).ToString()
@”
NAME:
$strScriptFileName
EXAMPLE:
C:\PS> .\$strScriptFileName -inputfile `”file name.csv`”
“@
}
If (-not $inputFile) {Usage;Exit}
#Get MSO creds and initialize session
If ($cred -eq $NULL) {$Global:cred = Get-Credential}
#
If ($ExchRemoteCmdlets.AccessMode -ne “ReadWrite”)
{
Write-Host
type-Host Connecting to Office 365…
Write-Host
$NewSession = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $cred -Authentication Basic -AllowRedirection
$Global:ExchRemoteCmdlets = Import-PSSession $NewSession
}
#Import the CSV file
$csv = Import-CSV $inputfile
#Create Rooms contained in the CSV file
$csv | foreach-object{
New-mailbox -Name $_.RoomName -room -primarysmtpaddress $_.RoomSMTPAddress -resourcecapacity $_.RoomCapacity
}
END OF CREATE-ROOMS.PS1
Step 5: Delete the Secondary Addresses from O365 Mailboxes
Run these commands:
#Script: remove-proxy.ps1
#Description:*** RUN THIS SCRIPT FROM A WINDOWS POWERSHELL SESSION ***
