Enterprise Vault Search (EVS) button will not work after applying patch.  No errors will show. 

Client trace will reveal (for Enterprise Vault Search):

11/10/2017 17:58:36.066[2272][H]: Action: Failed to execute action 'SEARCH'
11/10/2017 17:58:36.067[2272][H]: Action: A COM error exception has been caught: <this error code varies>

NOTE:  Legacy search functions such as Search Vaults and Archive Explorer are also affected. These buttons will not work as well, and the same workaround can be applied.

Client trace will reveal (for Archive Explorer):

13/12/2017 06:19:02.938[3428][H]: Action: Failed to execute action 'AE'
13/12/2017 06:19:02.938[3428][H]: Action: A COM error exception has been caught: <this error code varies>

To determine if this patch has been installed, this command may be run from an elevated command prompt ( Run as Administrator):

                systeminfo | findstr “KB4011196 KB4011178 KB4011162”


This issue has been resolved as part of the following release:

Enterprise Vault 12.2.2

NOTE:  After installing the Enterprise Vault 12.2.2 Outlook Addin Client, Outlook will have to be started for changes to be applied and then restarted to take affect.



Use the EnableRoamingFolderHomepages registry value to re-enable the Enterprise Vault Search button. This Microsoft KB article describes the usage of this registry value setting as it applies to this issue. This value type should be DWORD and set with a value of 1. 

The Registry location for these settings varies by the version of Outlook. For convenience, Veritas has made available a downloadable zip file containing Registry Entries (.reg) files to create the required settings on each supported version of Outlook.

To create the Registry settings on an affected machine: 
  1. Download the zip file attached to this article and extract it.
  2. Browse to the folder for the appropriate version of Outlook.
  3. On the affected workstation, import the contents of the .reg file by double-clicking it or by using File > Import from the Regedit application.
  4. Restart Outlook on the affected workstation.
The Registry settings can also be applied to a large number of machines using Group Policy.

As an alternative to modifying the Registry, users can also access their archived items via Enterprise Vault Search in a supported web browser or could choose to remove the security patch.
