Ok so I am going from Exchange 365 to Exchange 2013 on premise server, I am considering using Hybrid mode but I have some questions.
1.) Once I run the Hybrid Wizard I take it 365 and on premise will be linked, but will my 365 users be affected? Will they still be able to send and receive email as before?
2.) Do I need to enter a Send connector for the on premise users\server?
3.) Do I need to change any MX records?
4.) Can I then migrate my 365 user back to Exchange 2013
5.) What happens when I cancel the 365 subscription which is ultimately what will happen.
