there is a GetMailTips operation that returns MaxMessageSize element

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

Request:

<?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> [email protected] </t:EmailAddress> 
        <t:RoutingType>SMTP</t:RoutingType> 
      </SendingAs>
