I was using Groupwise in 2007 at a previous employer, and PGP was definitely easy to use with Groupwise. I worked in a MIS department for a large UK company, and the customer services department was in a small town in Wales, the kind of town where not many people had broadband in 2007, and the staff were not trained in any technical specialty, it was mostly just people with jobs instead of people with careers. The staff used to send banking information using PGP and Groupwise and people rarely had issues.

The problem now is the increasing number of centralised services, Google doesn't want to be storing encrypted emails within Gmail, because the content cannot be analysed for advertising purposes. And the same goes for other free email providers. It's still possible, but it is increasingly difficult.
