hi
i have a client, (200 end users) who wants to have a digital signature added to all emails leaving the company.
the exchange server is exchange 2010, and the outlook version on the clients pcs is a mix of outlook 2007 - 2013.
obviously, they are looking for a free solution, but in reality does such a thing exist?
or, would they have to go down the route of installing "active directory certificate services" on their domain
any suggestions appreciated.
