Been using Microsoft's Outlook for neigh on 25 years now but I have finally decided to frack it right off and find a new e-mail client!
They have forced a "new and improved" outlook on us which basically has adds in it unless you pay for a premium version of it.
I mean what is the point of blocking spam e-mails when they go and add their own?

Anyway I've since switched to a client called eM Client which has all the functionality of the old Outlook and none of the adds!

I'm using Mozilla Thunderbird as my email client.

I've been still using Outlook in my personal computer. Mostly because my employer offers office license for personal use too.

@FSB: Are you using the Windows based Microsoft Mail or the Microsoft Outlook that is part of Microsoft Office?
