Installing the Outlook Add-in

There are two ways to install the add-in:

• Setup file The setup automatically installs all required components. This includes the required Microsoft .NET Framework 4.8, the Microsoft Visual Studio 2010 Tools for Office Runtime, and the actual add-in, and Setup guides you through all the necessary steps and ensures that all prerequisites for a successful installation are met.
• MSI file The MSI file is required when using automatic software distribution. First the Microsoft .NET Framework 4.8, then the Microsoft Visual Studio 2010 Tools for Office Runtime and finally the MSI file with the actual add-in must be installed. The actual installation depends on the software distribution used.

NOTE: If you install the Outlook Add-in via MSI file, this must be located on a local hard disk. Installation via a UNC path is not possible.

NOTE: If you have installed NoSpamProxy and Microsoft Exchange on the same server, before installing or upgrading the Microsoft .NET framework, make sure that the appropriate version of the framework is supported by Exchange. For an overview of supported versions, see the Exchange Server Supportability Matrix.
