CodeTwo Email Signatures for Office 365.
The trial version of CodeTwo Email Signatures for Email Clients works for 30 days for an unlimited number of mailboxes. During this period, the program works in the same way as the full version but with one limitation: it adds additional information on the software and the manufacturer to outgoing messages. When the 30 days are over, the software will cease to work and you won't be able to update your signatures - it needs to be activated with a purchased license key. Note that although the trial period is over and you cannot create any new signatures yet update them on email clients encompassed by the policies, the signatures created during the trial period will continue to work until manually removed from your email clients.
Activation - this article describes the activation procedure of the program.
