> It seems to make a lot of sense: 80% of the people use 20% of the features. So you convince yourself that you only need to implement 20% of the features, and you can still sell 80% as many copies.
“Unfortunately, it’s never the same 20%. Everybody uses a different set of features
I've witnessed first hand how incredibly necessary those security features really are.
For example, installing mail server software on either Windows or Linux is trivial.
Actually operating a mail domain of any import securely in the face of determined attackers, dumbass insiders that will click anything, and constantly changing anti-SPAM technologies and standards is a full-time job all by itself.
This is why businesses rely on Microsoft 365 or G Suite.
One of the bonus features being your email is much less likely to disappear within Outlook.com's mailservers. Not sure what is going sideways there, but those mailservers are not reliable and mail traces are ineffective in finding lost emails that have proof of delivery to the MX record listed outlook.com mailserver.
