Increasing the max upload file size for SharePoint 2007

By default Microsoft Office Server 2007 limits uploads to files that are 50MB or less in size.

This limit can be increased, though it requires changes in both SharePoint and the IIS web server.

Here's how to increase the limit:

RDP to the web server(s)

SharePoint Settings

From the Start Menu open Administrative Tools > SharePoint 3.0 Central Administration

Go into Application Management

Choose Web Application General Settings

Ensure you choose the correct Web Application for which you wish to increase the limit

Increase the Maximum Upload Size to 2047

Ensure that, at the bottom of the page, you click OK

IIS Settings

From the Start Menu open Administrative Tools > Internet Information Services (IIS) Manager

Expand the server name, then Sites folder and choose the appropriate SharePoint website

Double-click Configuration Editor

Navigate to the system.webServer/security/requestFiltering section

Expand requestLimits

Set maxAllowedContentLength to be 2147483647

Then in the top right click Apply

IIS Reset

From the Start Menu, open a command prompt and enter iisreset

Wait for IIS to be restarted
