MicrosoftAbdul Farooque - So If I use UPN to sync my users but their SMTP is different, still my users can login to azure/office 365 with their SMTP email id, right?
Yes, users will have the option to use UPN or SMTP Proxy Address. Which ever is easiest for the user.
Do I must sync my email domain to accomplish this or just verify the domain in office 365 ?
You would need to verify the domain in Azure AD for the Proxy address to by synced to the user object.
To get a full list of requirements and limitations review our docs here: https://docs.microsoft.com/en-us/azure/active-directory/authentication/howto-authentication-use-email-signin#synchronize-sign-in-email-addresses-to-azure-ad
patrick410 - does this function work when logging in O365 connected workstations?
I will provide an update on this question.
belaie - It would be cool if all Microsoft login screen text should say "username" not an email address to log in, which would help users following company's internal username policy (email or UPN) to login to the cloud services.
This is a great suggestions for us to consider, would love for you to add this suggestion to our user voice :

hobbycat - However, it uncovered something that I would like clarity on, if there is contention between a UPN (cloud only account) and a proxy/email address on a sync'd account for example - which will take precedence? This is not a situation that I was expecting to encounter but it existed. From some the limited testing, it appears the account with email address wins, whereas I would have expected the UPN to take precedence.
I will provide an update on this question.
There was also a delay of upwards 20 minutes from creating the policy to seeing the change in behaviour. If this is expected then it would be helpful if the documentation reflected this.
Yes, this is expected to take up to 1 hour to see expected behavior. We will update our documentation to include this note. thank you
pmahlmann - This feature will allow us to change the UPN in one domain and then use email to log into Azure/Office365. when will this be GA.
We are looking to get a much customer feedback during preview before going GA. We do not have a target date currently.
csmithscf - It was a super simple change, just took a small amount of time (would recommend to update documentation - I'll comment on that article as well). Thanks again, such a great feature!
Thank you for the feedback, will be adding this to our documentation.
