When logging in as anyt user on test machine I am unable to enable the virtual vault following a successful download of the vault cache. The error message is - Enterprise Vault could not add or remove the following Virtual Vaults:
Try again later.
This is similar to article - http://support.veritas.com/docs/336989 (Virtual Vault fails to launch as the application cannot locate the MAPI provider information for the information store)
However the article suggests that a client trace will show up -  Could not create an instance of Virtual Vault. Verify that EVMSP is correctly configured in MAPISVC.INF: 0x8004010F
 ~EVMSPConfig::AddEVMSPService: 0x8004010F
However mine doesnt and the workarounds dont work for me:
The locale must be the same for Outlook, Virtual Vault and the Operating System.
Add the user account that is accessing Virtual Vault 'Power User' rights to the locale folder path. (For example, a Dutch locale path would be c:\program files\Common Files\System\MSMAPI\1043)
I can confirm the locales are all the same although this was working for this user until I upgraded to Outlook 2007 from 2003 and reset the vault cache.
Any help much appreciated.
