Why use Crossware for your Office 365 email signature?

With Crossware Mail Signature your Office 365 email signature is added in a secure closed loop and authenticated by standard Microsoft Office 365 protocol. This means that your email never leaves the Microsoft cloud and you will not need to use any specific email client or app.
