These users? You couldn't even email them from Outlook until just last year, 2016! How many users in the world would have accepted having an email account that no one using Exchange servers could handle? That cuts you (the user) off from hundreds of millions of people on corporate networks.

Arguably an advantage.

It's not just Exchange. RFC6530 support is pretty spotty.

Fastmail, which is pretty popular here, only allows a-z0-9_ in usernames. I don't see a "250 SMTPUTF8" reply when I connect to their server and EHLO. So, it's likely they don't support it either.

I use Fastmail and have sent myself a testing email with non-ASCII emails, like with Korean or Chinese characters. So 안녕@mydomain works with Fastmail.

So apparently if you host your own domain with them they do?

However, they don't appear to support it for [email protected]. Either for sign up, or for live delivery. http://imgur.com/a/Otf4f (see both images)

Try sending to 안녕@mydomain from a gmail account...it looks like they may not be supporting SMTPUTF8 correctly. Which could result in sending-to-yourself working, but not from an outside source.

I suppose... until you apply for a job and can't receive a favorable response because they're one of the many Fortune 5000 companies that use Exchange/Outlook somewhere in their infrastructure.

Not every one of my email-addresses is used in a business-context.
