Comments about Microsoft Outlook as an Alternative to Thunderbird
As a Firefox user, I have tried to love Thunderbird but it just can't compete with Outlook, IMHO.
It works. Much less buggy. Better integration with Windows. Encryption/Signing.Works over remote desktop without losing pieces of itself. Search is crappier though.
Not open source, not privacy-focused, no Linux support
outlook is clumsy and bloated and does nothing well. tbird does one thing and well.
Outlook do not support RSS
