A new check added to Enterprise Vault 8 Service Pack 3 is around OUTLVBS.DLL. Our forms don’t work without this DLL, so it’s kind of important. If you using the Outlook Addin from EV 8 SP 3 or later, and OUTLVBS.DLL can not be found in the same folder as Outlook.exe, then you will see the following pop-up.
A “quick way” to correct this is to copy the .DLL from another machine to the same folder as Outlook.exe, and restart Outlook. That should fix it. There are of course other methods, which may be listed on Microsoft’s knowledgebase.
