I have a custom domain outlook.com account which was created years ago and now it can't be managed through domains.live.com, lets say it is:
I would like to subscribe Office 365 for Business and add my domain into it to manage all my accounts and emails, including that [email protected].
What happen with all of my emails, contacts, calendar, and other data, which are currently linked with [email protected] (old custom domain outlook.com account) after adding it to Office 365 subscription?
Would it be erased so I will never see my current data?
