Installation and configuration

The software's engine runs entirely in the cloud and signatures are added server-side. The program only requires an initial setup by a global administrator of your Office 365 organization. This is done via a web-based component called CodeTwo Admin Panel, and includes configuration of your tenant and its Exchange Online connectors. After that, a ClickOnce application, the Manage Signatures App, needs to be installed to create and apply signature rules in your environment. Click the links below to learn more.
