Office 365 implementation with current email address.

[KedarHukeri]

I am planning to set up office 365. for example, my organization domain name is ABC.com

The organization is using MS exchange and have all users with firstname.lastname@abc.com

When I am trying to create their office 365 ID- I am getting the option of firstname.lastname@abc.onmicrosoft.com  as the email address.

Do we have any better way of doing this? Can I keep the same email address ( firstname.lastname@abc.com) and still move all the users to Office 365? 

I am searching the previous posts and doing google, but if someone has faced a similar issue.

Thank you,

you need to add and verify abc.com in O365 first. Login using below and follow the prompts to add the domain in O365 :-
https://admin.microsoft.com/Adminportal/Home?source=applauncher#/Domains

Just add and verify the domain, adding the records such as MX will start routing your emails to O365.
