Here is the solution by the VMware Support:
>>>>>>
Change the following registry value on the master image.
Key
HKLM\SYSTEM\CurrentControlSet\services\svdriver\Parameters
Value EnableHookInjection
Data 1 <<< Here it needs to be changed to 0.
It can also be done using the command line.
reg add HKLM\SYSTEM\CurrentControlSet\services\svdriver\Parameters /v
EnableHookInjection /t REG_DWORD /d 0 /f
Once done , Reboot the Agent VM and try the Outlook test again. If
you are using Instant Clones, or Linked Clones with refresh at logoff, you may
need to create a new base image in order to test.
