EWS删除联系人上的电话号码条目 [英] EWS Delete PhoneNumber Entry on Contact

问题描述

我尝试在使用ExchangeWebService和powershell时删除联系人中的电话号码条目。

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

我可以使用数字创建新的联系人，依此类推。我什至可以更改这些数字。但是我可以将其设置为 $ null 或 。

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

它总是给我用 1作为参数调用 Update的异常：更改描述中的对象必须包含一个且只能更改一个属性。

我知道即时消息不允许将其设置为或null。但是必须有一种删除电话号码条目的方法。

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.

因此，可能有人在那里帮助我解决此问题。

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

到目前为止，我检查电话号码是否有更改，仅在有更改的地方进行更新。

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)

问题出在此行 $ c.PhoneNumbers [$ enumBusinessPhoneValue ] = 即使我放入 $ null 我也遇到相同的错误。

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

推荐答案

在这种情况下，您需要使用商务电话的扩展属性（这是与EmailAdddresses > https://blogs.msdn.microsoft.com/emeamsgdev/2012/05/17/ews-managed-api-how-to-remove-email1-email2-email3-来自），例如

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)
