I am wondering if\how the situation below would be possible.
Company.com has an existing Exchange 2003 on premise environment with external access via owa.company.com etc.
Company.com deploys a new Hybrid Echange 2010 SP2 RU3 server. This server is pubished with different url's, such as hybrid.company.com etc.
Can co-existence features (minus of course URL re-direction for Office 365) exist in this fashion? We do not want to alter the existing production mail flow while building and migrating users.
