ExSign Portal is the signature management interface for the ExSign cloud service for Microsoft 365. It is where you create rules for your signatures and disclaimers, and design signatures with the help of an editor. Signatures can be designed from scratch or can be selected from pre-built signature templates. 

You can sign in to the ExSign Portal with your Microsoft credentials and will be redirected to it through the Billing Portal. For details refer to following sections:
