Folgendes Skript ist NICHT von mir, sonder von “Dave Stork – @dmstork – dave.stork at ogd.nl”
Ich möchte es an dieser Stelle hier teilen, da es mir sehr geholfen hat:
### Convert-MailUser.ps1
### Version 1.0 20130429
### Dave Stork - @dmstork - dave.stork at ogd.nl
### Script 'upgrades' an existing mail enabled user and converts it to a mailbox enabled user
### Existing SMTP addresses will be maintained, if the SMTP domain is an Accepted Domain
### As an option the Forwarding SMTP address can be set, so that mail is deliverd in mailbox and forwarded
param(
[Parameter(Position=0,Mandatory=$True,ValueFromPipeline=$True)]
[string]$Identity,
[Parameter(Position=1,Mandatory=$False,ValueFromPipeline=$True)]
[switch]$KeepForwarding
)
### Organizational information
$AcceptedDomains = Get-AcceptedDomain
$AcceptedDomains = $AcceptedDomains.DomainName
$AcceptedDomains = $AcceptedDomains.Domain
### Check wether this is actually a mail enabled user
### Exit when RecipientType is a MailUser
$User = Get-User $Identity -ErrorAction SilentlyContinue
$RecipientType = $User.RecipientType
If ($RecipientType -ne "MailUser") {
Write-Output "$Identity is not a Mail Enabled user, but a $RecipientType. Nothing has been changed."
Exit
}
### Store relevant information
$MailUser = Get-MailUser $Identity
$SMTPValues = $MailUser.EmailAddresses
$SMTPValues = $SMTPValues.SmtpAddress
$SMTPExternal = $MailUser.ExternalEmailAddress
$SMTPPrimary = $MailUser.PrimarySmtpAddress
$Alias = $MailUser.Alias
### Mail disable MailUser without the need for confirmation. Account is now a normal AD user.
Disable-MailUser $Identity -Confirm:$False
### Now Mailbox enable the same user with same Alias as when it was a mail user
Enable-Mailbox -Identity $Identity -Alias $Alias
### Check what the current PrimarySMTPAddress is and compare it to the Mail User
$Mailbox = Get-Mailbox $Identity
$MailboxPrimarySMTP = $Mailbox.PrimarySMTPAddress
If ($MailboxPrimarySMTP -ne $SMTPPrimary) {
Write-Host "Warning! The Mailbox Reply SMTP differs from the Primary SMTP as when the user was mail enabled." -foregroundcolor "Red"
Write-Host "Check whether this should be the case and whether the correct Email Addres Policy has been applied." -foregroundcolor "Red"
} else {
Write-Host "Informational: Mailbox Reply SMTP is the same as the Primary SMTP when the user was mail enabled:$MailboxPrimarySMTP"
}
### Now we have to check and add all other SMTP Addresses.
$CounterA = 0
ForEach ($SMTPAddress in $SMTPValues){
$SMTPAddress = $SMTPValues[$CounterA]
$CounterB = 0
$AmountSMTPAdded = 0
ForEach ($AcceptedDomain in $AcceptedDomains) {
$AcceptedDomain = $AcceptedDomains[$CounterB]
### Check whether the SMTP addres falls within the configured accepted domains
If ($SMTPAddress.ToLower().EndsWith("$AcceptedDomain")) {
### Check whether the SMTP Address is the current Reply SMTP and thus already added
If ($SMTPAddress -ne $MailboxPrimarySMTP) {
Set-Mailbox –identity $Identity -EmailAddresses @{Add="$SMTPAddress"}
Write-Host "$SMTPAddress has been added as an SMTP Addres to $Identity"
$AmountSMTPAdded = $AmountSMTPAdded + 1
} else {
If ($SMTPAddress -eq $MailboxPrimarySMTP) {
$AmountSMTPAdded = $AmountSMTPAdded + 1
}
}
}
$CounterB = $CounterB + 1
}
$CounterA = $CounterA + 1
If ($AmountSMTPAdded -eq 0) {
Write-Host "Informational: $SMTPAddress does not correspond with any Accepted Domain and has not been added." -foregroundcolor "Yellow"
}
}
### If optional parameter KeepForwarding is set to $True, the Forwarding SMTP Address will be set
### Mail will be delivered to mailbox and to external address
If ($KeepForwarding -eq $True) {
Set-Mailbox -Identity $Identity -ForwardingSmtpAddress $SMTPExternal -DeliverToMailboxAndForward $True
Write-Host "Mail for $Identity will be delivered to the mailbox AND forwarded to $SMTPExternal"
}
