Software :: What Is The Closest Mail Program To Outlook

I use Thunderbird. I find that without using a ton of plugins I can not get Thunderbird to do remotely close to what Outlook does out of the box. Truth be told the Microsoft Office suite is a really good suite of products, especially Outlook and it's integration with Word. I hate how is Thunderbird you have to have a plugin to have a calendar, and then being able to schedule appointments with people is a whole other project.

Also if you Forward an email it just creates a new email with the forwarding email attached as a .eml file. When that happens you get into compatibility of the recipient being able to read it (mainly web mail users). It is little things like that I get worked up about, but I have found Thunderbird is the closest open source client to outlook to manage my mail. I personally would like to find a client more like Microsoft Outlook that I can run natively on Debian.
