I just started working for a company that has somewhat implemented Office 365 to about 100 users. They are mostly using it for Exchange Online. No ADFS or AD Sync has been done between the on-premise domain and Office365.
The same user accounts do exist in the local domain.
Once we get ADFS and AD Sync working what will happen between the Office365 accounts and the local accounts. For instance, in Office365 we havejanedoe@testdomain.com and locally we have a userjanedoe@testdomain.com. Will the accounts just sync together and use the information from the local domain since the IDs are the same.
