Exchange Server 2007 has a default maximum accepted request length of 13MB that it can accept. You may increase the maximum accepted request length by performing the following:

  1. Open Windows Explorer
  2. Navigate to C:\Program Files\Microsoft\Exchange Server\ClientAccess\exchweb\ews
  3. Open the file Web.Config in a text editor such as Notepad
  4. Find the XML tag starting with maxRequestLength=
  5. Change the existing value to maxRequestLength="102400"
  6. Save the file
  7. Note: a value of 102400 represents 100 MBs in kilobytes

 

Sample Web.Config before changes:

<configuration>
<system.web>
...
...
<httpRuntime maxRequestLength="13280" />
</system.web>
</configuration>

Sample Web.Config after changes:

<configuration>
<system.web>
...
...
<httpRuntime maxRequestLength="102400" />
</system.web>
</configuration>
