I have found Enigmail and Thunderbird to be easy and intuitive. Both are open source. Thunderbird is the email client and Enigmail is the plug-in.

If your work does not require you to use the proprietary exchange stuff in Outlook I would say that Thunderbird with Enigmail is a really convenient solution for encrypted and signed email. Once set up there is very little overhead involved, and if a recipient's email address is in your local gpg database Enigmail will happily encrypt content by default.

Kinda does require the proprietary solution. We do have in the office a paid for Thunderbird plugin (we use Ubuntu unless working on .NET) but for personal use (at home reading work mail) I am limited to using mail on my Macbook Air. Also explaining the process to someone else I know vs just telling them to install an all inclusive mail client that is more seamless would be a different story. Short of telling the whole world to sign up for ProtonMail I would love to see a client that handles email encryption cleanly.

Now try getting your compute newb friend/family going so they can sign, verify signatures, encrypt, decrypt, add keys, etc.

Now try web of trust, key servers, revoking certs.

Then the finer points of what to when you find tons of different keys for people with the same name.

Then subkeys, short term keys, and keeping long term keys offline.

See.. easy!
