I have gmail at home and also used it for 11 years in my last job.
Six months ago I moved to a new job where they use Outlook and I still can't get my head around it. The search function is useless. If you've replied to someone you have to open the original email and click "view conversation" to see your reply. I created a folder in Outlook yesterday to move some important stuff I wanted to keep - today that folder has disappeared!
Outlook! Grrr! What is it good for?
