Error Message

After having authenticated with the Identity Provider (IdP) few scripts errors do appear like

'An error has occurred in the script of this page.'

Error: '$' is undefined 

or 

Error: 'Sys' is undefined

then Enterprise Vault Search does not load properly and it is not usable by users

After the authentication with the compliant Identity Provider the embedded Microsoft Outlook browser stops the execution of some scripts because they are in different Internet Zones https://docs.microsoft.com/en-us/troubleshoot/browsers/ie-security-zones-registry-entries#notes-about-1200-1a00-1a10-1e05-1c00-and-2000

The aforementioned issue does not occur if the 'Search Behaviour' in 'Exchange Desktop Policy | Advanced | Outlook' is set to 'Separate Browser'

In case it is desired to have the 'Search Behavior' to 'In Outlook' the following workaround can be implemented:

1. on the affected clients add the IdP domain (such as *.okta.com) like a trusted site like

or add the same domain in the registry key 'Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\okta.com' like 

3. In addition it is necessary to implement such registry keys (either manually editing the registry on the client with admin privileges or via a GPO policy update)

• Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\4\1A10 
  • from 3 to 0 
• Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\4\1A10
  • from 3 to 0 

the zone setting 1A10 value to 3 corresponds to 'Block all cookies' while the value 0 corresponds to 'Accept all cookies'
