Thanks four your quick reply.
The idea is, to give the user the possibility to create a personal signature, based on several templates. That happens on a website.
The user then copies the signature manually to the corresponding dialog. So it would be easier, if the user must not navigate through the menus.
I couldn’t find a way to set a signature by code. The token you suggest, has not the functionality I need. (A user could have more than one signature for example.) I know it might work with SOAP, but I couldn’t find proper documentation and it seems to be too complex, compared to the output.
