3. Locate the following line in the web.config file.
   
   httpRuntime maxRequestLength="10240" executionTimeout="3600" requestValidationMode="2.0"
   
   
   
   Note: The above value is in the KB. By default, the attachment size in MailEnable is 10 MB which is equal to 10240 KB.
   
   
4. To increase the attachment size, you need to modify the value of the maxRequestLenght. For example, if you wish to increase the attachment size to 20 MB then you need to set the value of the maxRequestLength to 20480.

5. If you are using IIS 7.0 or later, then you will also need to add the following lines under the system.webServer section.
   
   
   
   security
   requestfiltering
   requestlimits maxallowedcontentlength="10240000"
   /requestfiltering
   /security
   
   The value for maxAllowedContentLength is in bytes, so it will be different from the maxRequestLength size.
   
   
6. Like, if you wish to set 20 MB then you need to set maxAllowedcontentlength to 204800000.
