You can edit the Web.config file to enable large messages to be sent using Outlook Web App.

The admin needs to edit the web.config file (program files, microsoft, exchange server, clientaccess, owa) and change the size. Save file then restart Exchange server.

The issue would be resolved.

Use Notepad to change the maxRequestLength value

You need to be assigned permissions before you can perform this procedure.

   1. Find the Outlook Web App Web.config file on the Client Access server. The default location is <drive>\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa.

   2. Make a backup copy of the file.

   3. Find maxRequestLength and change it to the value that you want. The value is stored in kilobytes (KB). The default value is 35000. The following example shows the maxRequestLength value in the Web.config file.
      <httpRuntime maxRequestLength="35000" />

   4. Save and close the file.

Sorry about thatl  I did not mean to ruffle any feathers.  That was actually only part of the solution as I had to manually set things using the ESM.

@DFKE :- DF whatever your name is, before posting it is good to search some sites and check some articles and not just blindly paste any thing from ourselves that would create a big trouble on the users environment.

so from where you have seen that i have just coped any link n paste in it, its just a simple step.

@Stacy :- have u followed the above steps and is the issue being resolved ?

Please post
