Just a little script I put together during the week to update primary email address on a user account that is been synced over to Office 365 (O365) from Active Directory (AD). It’s not in any way a perfect script but gets the work done. Download script here
Syntax:
.\UpdatePE.ps1 -NewDomain azure.hazelnest.com -Address hhazeley@o365.hazelnest.com -KeepCurrentPrimary .\UpdatePE.ps1 -NewDomain azure.hazelnest.com -KeepCurrentPrimary .\UpdatePE.ps1 -NewDomain azure.hazelnest.com .\UpdatePE.ps1 -NewDomain azure.hazelnest.com -Address hhazeley@o365.hazelnest.com

$NewAddress = $ADUser.userprincipalname -replace "@.*","@$newdomain"
#updates information in proxyaddresses string
$ADUser.proxyAddresses.Remove("SMTP:$Eaddress")
$ADUser.proxyAddresses.Remove("smtp:$NewAddress")
$ADUser.proxyAddresses.Add("SMTP:$NewAddress")
#Readds old primary as secondary address
If ($KeepCurrentPrimary.IsPresent)
{
$ADUser.proxyAddresses.Add("smtp:$Eaddress")
}
#Set proxyaddress string into a variable
$NewProxyAddresses = $ADUser.proxyAddresses
#clear proxaddresses on account
$ADUser | Set-ADUser -Clear proxyaddresses

ForEach ($NewProxyAddress in $NewProxyAddresses)
{

}
#Updates other mail attributes on account
