.Net EWS將郵件發送到ContactGroup

Question

我創建了一個聯繫人組，並且當我將聯繫人組的名稱作爲EWS中的收件人發送時，它會給出以下異常「一個或多個收件人無效」。

我一直在尋找答案，並沒有很多的EWS聯繫人組的用法。

任何線索？

Answer 1

我做了一些研究，找到了我的答案。這是任何需要它的人的解決方案。

 
//Setup ContactGroup EmailAddress 
EmailAddress emailAddress = new EmailAddress(); 
emailAddress.MailboxType = MailboxType.ContactGroup;        
emailAddress.Id = ItemID; 
message.ToRecipients.Add(emailAddress); 

//You can get the ItemID with the following code. 

// Instantiate the item view with the number of items to retrieve from the Contacts folder. 
ItemView view = new ItemView(9999); 

// Request the items in the Contacts folder that have the properties that you selected. 
FindItemsResults contactItems = ExchangeService.FindItems(WellKnownFolderName.Contacts, view); 

// Loop through all contacts 
foreach (Item item in contactItems) 
{ 
    //Check to see if ContactGroup 
    if (item is ContactGroup) 
    { 
     //Get the contact group 
     ContactGroup contactGroup = item as ContactGroup; 
    } 
}
