Hi Memebers,

In My server 2012 one AD is already running.. with two Domain Controller.
We have purchase a New Office 365 license..
For testing purpose.. we have created few user in New Office AD.

Now I want to Directory sync my Old Active Directory to Office 365 Directory.. so that both Domain can exist in New

What is the correct process to create all these accounts in 365 AD, enable sync but not have these AD accounts break/overwrite newly created Office 365 accounts (and groups).

Regards,
Sue Zen Chin
