Rights Management, Protection, and Email AutoSignatures

 

Given the increased ways to apply rights management protection (encryption) to Exchange Online messages, the volume of encrypted traffic should rise. That's good for users because their email is protected, but it's not so good for ISVs who must deal with encrypted email. One such example is autosignature products, where server-based components can't touch protected email to add their text.
