The cause of this error is the failure to properly register the StorageOnlineOpns.dll file on the DA server.
On the Discovery Accelerator server register StorageOnlineOpns.dll with Regsvr32.exe
From a command prompt, type (where Enterprise Vault is installed to default installation path)
regsvr32.exe "C:\Program Filesx86\Enterprise Vault\StorageOnlineOpns.dll"
If Enterprise Vault is not installed to the default installation path, change the drive letter and path to the where Enterprise Vault is installed.
