EWS Delete PhoneNumber Entry on Contact

问题

I try to Delete an phone number Entry within an contact while using the ExchangeWebService and powershell.

I can create new Contacts with Numbers and so on. I can even change those numbers. But i can set then to $null or "".

It always gives me Exception calling "Update" with "1" argument(s): "An object within a change description must contain one and only one property to modify."

I understand that im not allowed to set it to "" or null. But there have to be a way to delete a phone number entry.

So may be there is someone out there to help me with this issue.

So far i check if there is a change in the phone number and only update it where there is.

$enumBusinessPhoneValue = [Microsoft.Exchange.WebServices.Data.PhoneNumberKey]::BusinessPhone
if($c.PhoneNumbers[$enumBusinessPhoneValue] -ne "" -and $c.PhoneNumbers[$enumBusinessPhoneValue] -ne $null){
    if($busPhone -ne ""){
        if($c.PhoneNumbers[$enumBusinessPhoneValue] -ne $busPhone){
            echo "="
            $c.PhoneNumbers[$enumBusinessPhoneValue] = $busPhone
        }
    } else {
        $c.PhoneNumbers[$enumBusinessPhoneValue] = ""
    }
} else {
    if($busPhone -ne ""){
        $c.PhoneNumbers[$enumBusinessPhoneValue] = $busPhone
    }
}
$c.Update([Microsoft.Exchange.WebServices.Data.ConflictResolutionMode]::AlwaysOverwrite)

The problem lies in this line $c.PhoneNumbers[$enumBusinessPhoneValue] = "" even if i put in $null i get the same error.

You need to use the Extended Property for the Business Phone in this case (this is the same as for EmailAdddresses https://blogs.msdn.microsoft.com/emeamsgdev/2012/05/17/ews-managed-api-how-to-remove-email1-email2-email3-from-a-contact/) eg

$PidTagBusinessTelephoneNumber = new-object Microsoft.Exchange.WebServices.Data.ExtendedPropertyDefinition(0x3A08,[Microsoft.Exchange.WebServices.Data.MapiPropertyType]::String);
$c.RemoveExtendedProperty($PidTagBusinessTelephoneNumber)
$c.Update([Microsoft.Exchange.WebServices.Data.ConflictResolutionMode]::AlwaysOverwrite)
