I currently have Microsoft Outlook 2013 version but I am going to buy a new laptop soon and probably sell the old one. What are some FULLY featured alternatvies paid or free. Obviously I want something that's very similar to Microsoft Outlook. I am not looking for anything as basic as postbox or something that is no longer updated such as Thunderbird. I don't mind paying money but for a license that's transferable from computer to computer. I wish there was Open Office equivalent of Outlook but there isn't. So what are my options besides paying for a license to Microsoft every time I buy a new laptop.
