Cause

The Exchange 2013 server is not configured for receiving large items through Exchange Web Services (EWS)

Solution

1. Increase the message size limits:
   

   Open the Exchange Management Shell (EMS) and enter the following:

   Set-TransportConfig -MaxReceiveSize 100MB -MaxSendSize 100MB

   Get-SendConnector | Set-SendConnector -MaxMessageSize 100MB

   Get-ReceiveConnector | Set-ReceiveConnector -MaxMessageSize 100MB

2. Increase the maximum accepted content length:
   

   Navigate to C:\Program Files\Microsoft\Exchange Server\v15\ClientAccess\exchweb\ews

   Open the file Web.Config in a text editor.

   Go to the end of the file and increase the "maxAllowedContentLength" value to "104857600"

   Save the changes.

3. In some cases it is necessary to increase the maximum received message size in WCF settings:
   

   Navigate to C:\Program Files\Microsoft\Exchange Server\v15\ClientAccess\exchweb\ews

   Open the file Web.Config in a text editor.

   Find all XML tags starting with maxReceivedMessageSize=

   Change the existing values to maxReceivedMessageSize="104857600"

   Save the changes.

   Open Command Prompt and type in: cd %windir%\system32\inetsrv

   Type: appcmd.exe set config "Default Web Site/ews" -section:requestFiltering -requestLimits.maxAllowedContentLength:104857600

   Restart IIS (Run iisreset in Command Prompt).

   Restart the Microsoft Exchange Transport service.
