I posted it on other threads becasue we're all in this mess...
I've been struggling with this issue for good few days.
I causes loads and loads of people contacting our stores saying that they do not know if the order was received.
Some start to claim that we're scamming them - taking the money and not even sending order confirmation.
So I came up with a temporary solution.
I use Zapier to use a walkaround to send emails via a different server. Not Shopify.
That way I think hotmail is accepting emails as they are not coming grom shopify smtp or whatever.
I recorded a video here on what to do: https://funneljar.com/hotmail
This video explains what to do so you can do it yourself.
For all the people who are not too tech savvy, I have a paid solution too.
Hope this helps
just got an update from shopify tech support
Apparently you just need to add some records to the DNS on your domain
