In the last few weeks, PocoSystems have greatly improved their email clients (Poco and Barca).
Barca 2 does not appear in the REVIEW section here and do believe it deserves a first look.
It has many features like Calendar, Tasks, Planner etc.
Search feature has been the major update and it performs incredibly well!
The back-up/restore feature is another handy asset that works just fine.
The price tag for a newcomer might be a bit too spicy, but i do prefer it to Outlook (not just for the price tag).
So much for my 2cents worth.
