Sending a large attachment in OWA 2010

When users attach an attachment bigger than 35MB in OWA 2010, the users get the following error:

404 - File or directory not found
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.

Remark: Assuming that your organization allows users sending the large attachment bigger than 35 MB.

To solve this problem, I need to modify the "web.config" file.

1. At the Client Access Server, log in as Domain Administrator.
2. Launch "Windows Explorer".
3. Navigate to "C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa".
4. Open "web.config" by "Notepad".
5. Search "requestLimits maxAllowedContentLength" and "httpRuntime maxRequestLength".

By default, the maximum attachement is about 35MB. I need to modify the value which is suitable for my environment.

6. Next to "requestLimits maxAllowedContentLength", change the value from "35000000" to "52428800".

Remark: The value is in byte(B).

7. Next to "httpRuntime maxRequestLength", change the value from "35000" to "51200".

Remark: The value is in Kilobyte(KB).

8. Save and exit the file.
