Answer 1

这取决于您的 Exchange 版本

来自微软 blog:

maxReceivedMessageSize (WCF) – Identifies the maximum message size that is accepted by EWS. This maximum message size is 35,000,000 bytes, which translates to 25 MB of base64-encoded data. Note: The values for this limit differ for an on-premise Exchange 2010 deployment. In the initial release version of Exchange 2010, the message size limit is 10 MB. In Exchange 2010 Service Pack 1 (SP1), the message size limit is 35 MB.

Answer 2

有一个 GetMailTips 操作 returns MaxMessageSize 元素

<t:MaxMessageSize xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">10485760</t:MaxMessageSize>

要求：

<?xml version="1.0" encoding="utf-8" ?> 
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
        xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
        xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"> 
  <soap:Header> 
    <t:RequestServerVersion Version="Exchange2010" /> 
  </soap:Header> 
  <soap:Body> 
    <GetMailTips xmlns="http://schemas.microsoft.com/exchange/services/2006/messages"> 
      <SendingAs> 
        <t:EmailAddress> user1@contoso.com </t:EmailAddress> 
        <t:RoutingType>SMTP</t:RoutingType> 
      </SendingAs> 
      <Recipients> 
        <t:Mailbox> 
          <t:EmailAddress> user2@contoso.com </t:EmailAddress> 
          <t:RoutingType>SMTP</t:RoutingType> 
        </t:Mailbox> 
      </Recipients> 
      <MailTipsRequested>All</MailTipsRequested> 
    </GetMailTips> 
  </soap:Body> 
</soap:Envelope>
