We have Exchange 2007 and want to go hybrid.
So we need an Exchange 2013 "hybrid" servers in co-existence with Exchange 2007.
Some questions i have;
- We need to switch CAS (autodiscover/ews/oa) to Exchange 2013. Do we need to configure Exchange 2007 with LEGACY url's and is a LEGACY url needed in an Exchange 2007/2013 hybrid Office 365 environment?
- If we keep users on Exhange 2007 can we move user mailboxes straight from Exchange 2007 to Office 365?
- Is it wiser/best-practise to first move to Exchange 2013 and fase out 2007 and then go hybrid?
