The first step in your installation is to import your employees onto the Letsignit platform. For this you can set up a synchronization with your company directory:

  1. Synchronization

The principle of this function is to be able to benefit from automatic synchronization for users declared on an On Premise infrastructure with Microsoft Active Directory type directory servers.


Letsignit must declare an application for the client (appId and appSecret provided) on the Letsignit infrastructure. Once declared, this application is allowed to run with our public API (reachable on https://api.letsignit.com).


The script provided is adaptable to the client's environment: it creates a connection to the local Active Directory (Microsoft), retrieves user data and pushes it through https protocol and JSON technology on the Letsignit Cloud middleware.


To benefit from this function automatically, it is possible to configure it as a planned task. It is necessary to have some PowerShell knowledge in order to configure the filters of the scripts.

If you would like to set this up on your Letsignit platform, here is the link to the technical documentation:


2. Push API

Once done you can also activate an API connector, this will allow you to benefit from your signature on Outlook Webmail (OWA).

3. SMTP

This function consists of redirecting the mail flow from the client’s local Exchange server(s) to the Letsignit infrastructures.

Once received by the Letsignit infrastructure, the email is signed according to the client’s configuration and is sent out to the client's relay host (spam-filter gateway type, outgoing filtering equipment), which must be reachable on a public IP. This relay can be located inside or outside of your infrastructure.


This function is accessible by making an appointment with our technical support team via the Letsignit web interface, by clicking on your account icon (top right corner) and then going in the 'Connectors' and SMTP menu. Click on ‘make an appointment with a technician’.

You will be contacted for an appointment.
