During a retrieval of an item through Outlook, the Enterprise Vault (EV) Outlook Add-in checks the individual components of the message header to confirm that all of the components of the item can be read.  This error can be caused if a portion of the Content Header of the message cannot be read. 

This has been observed specifically with the inability to read the Content-Length header of the item. 

The cause for this is due to a configuration issue with IIS on the EV  Server and 'Enable Buffering' being turned off on the Default Web Site.

The following Powershell script may be run on the EV Server, utilizing a link to an .asp file, to confirm that the Content-Length value can be read.

-----------------Copy below-------------------

$url = "http://EVServerName/EnterpriseVault/Search.asp";;
$xHTTP = new-object -com msxml2.xmlhttp;
$xHTTP.open("GET",$url,$false);
$xHTTP.send();
$xHTTP.status # returns the status code
$xHTTP.getResponseHeader('Content-Type')
$xHTTP.getResponseHeader('Content-Length')
$xHTTP.getResponseHeader('Server')

-----------------Copy above-------------------

Results:

200                             ------(Status Code)
application\msg        ------('Content-Type')
                                 <------ NO CONTENT-LENGTH
Microsoft-IIS/7.5       ------('Server')

 Using the script above, the results will show an empty result where the Content-Length Header information would be returned.

Confirm that Enable Buffering under the Default Web Site is enabled.

How to turn on 'Enable Buffering' under the ASP feature of the Default Web Site:

Internet Information Services (IIS) 7.5

1. Within Server Manager -> Roles -> Web Services, Select  IIS.
2. Expand Sites and select Default Web Site.
3. Under Default Web Site Home, under the IIS Area, open the ASP Feature.
4. Within the Behavior Properties section, confirm Enable Buffering is set to True. (Default value)

Internet Information Services (IIS) 6.0

1. Within Computer Management -> Services and Applications -> IIS, expand Web Sites.
2. Right Click Default Web Site and select Properties.
3. Select the Home Directory tab.
4. Under Application settings, select Configuration.
5. Under Application Configuration, select the Options tab.
6. Confirm Enable buffering is selected.
