More information

The Zetafax Outlook extensions can be installed on a Terminal Server system but the Microsoft components required to use them with Outlook are not installed when Outlook is installed on a terminal server system. This causes the Zetafax Outlook extensions to fail.

As well as the extensions failing, if you try to install the forms on the Microsoft Exchange server using an installation of Outlook on the terminal server system nothing will happen when you click on the "Install forms" Button.

To resolve this you should work through the following before installing the Zetafax Outlook Extensions:

Enabling Outlook to use forms with VBScript

When running the installation of Microsoft Office on a terminal server, the default MSI (Microsoft installer) package for office does not include support for VB script, also it cannot be selected as an option under custom installation. Microsoft has provided instructions on how add VB script support in this environment.

For more information on how to do this, please refer to the Microsoft knowledge base article


This article instructs you to copy the Outlvbs.dll file from a computer running Outlook that is not a Terminal Server to the corresponding folder of the affected Terminal Server computer.

NOTE: It is advisable that both systems should be running the exact same version of Outlook!

Installing the Zetafax Outlook Forms and Extensions

Once you have enabled Outlook to use forms with VBScript as above you need to then install the Zetafax Outlook Forms and Extensions as per ZTN1113
