原因
Microsoft made changes to Outlook to protect users from a possible security flaw that could result in malicious code running on their client machines. As a result certain functions within multiple third party products now have to be explicitly enabled to allow them to run correctly.
There was a change in the updates that now requires setting registry key(s) for the form to run.- Custom form script is, by default, now disabled across the board. The following registry key has a default value of 1, which indicates form script should not run:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Office\16.0\Outlook\Security::DisableCustomFormItemScript
To enable custom form scripts, this registry key must be created and set to 0.
- Once custom form scripts have been enabled at all, they must then be enabled per form message class. For instance, if you have a form with the message class IPM.Note.Custom, we must register "IPM.Note.Custom"
- Custom form script is, by default, now disabled across the board. The following registry key has a default value of 1, which indicates form script should not run:
