SharePoint Maximum Request Length Exceeded


Error: There was an exception running the extensions specified in the config file. ---> Maximum request length exceeded.


The files being sent are exceeding the limitations specified by SharePoint. 

SharePoint Maximum Request Length Exceeded (MaxRequestLength): 
You will need to modify your web.config and/or system.config files to have a higher MaxRequestLength property. 

Here is the MS article on how to accomplish this: 

We suggest setting it to something high enough to accommodate any files you may upload. Try starting with a value of 102400. 

1. Open Internet Information Services (IIS)
2. On the Server node, select Request Filtering
3. Click on Edit Feature Settings on the right sidebar
4. In the Maximum Allowed Content Length (Bytes) text box enter your value
5. Save Changes
6. Re-test the failing operation
