Increasing CRM Attachment File Size Limits

This morning i was working with one of my client where they, asked  Is there anyway to increase the size of the attachment in MS CRM?.
I was googling around the sites and finaly got the solution as below.

Purpose & Scope

CRM and IIS limit the size of attachments. This procedure describes how to set the max file size to a different value. It requires modifying the CRM web.config and the registry.


In the CRM Web.config, modify the following to provide appropriate values:

                                <httpRuntime executionTimeout=”999” maxRequestLength=’ 999999’/>                 <- try setting these 2 value to something higher as shown here (don’t change or remove other existing parameters)

In the Registry (care should be taken when modifying the registry as mistakes can render your system inoperable) navigate to HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSCRM and find maxuploadfilesize and change the value appropriately. The default is approximately 5 MB.

The lowest value of these two settings will rule.
