Issue:

While trying to load the Master Catalog to CA SAM via Exchange->Exchange Directory… but when I click on the "Upload File".. I get the following error(s): 

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

-or-

HTTP Error 404.13 – Not Found

The requested filtering module is configured to deny a request that exceeds the request content length.

Cause:

The 'requestLimits' in IIS 7 -> maxAllowedContentLegnth setting is too small / limited.

Resolution:

1) Open IIS 7

2) Click Server-> under Management select Configuration Editor

3) Open Deepest Path: MACHINE/WEBROOT/APPHOST AND EXPAND requestLimits

4) The default setting is 30000000; change this to 3000000000. SAVE setting.
