I am glad that you ditched Outlook for Thunderbird. I have using Thunderbird since God knows when. It is fast, easy to you and best part fully customizable. Ever since I started using it I have had 100s of computer crashes, resulting in 100s of OS re-install and changes. Never have I had any problems getting my mail,contacts and appointments back to the way they were before and all this was so easy. Only thing I am waiting for, is a mobile device with Thunderbird in it. I do not know of any. If you have any suggestions. Please feel to email me.
