The Office 365 Hybrid Configuration wizard has been updated to support Exchange 2010. This new wizard comes with the following advantages:
- An updated user experience that simplifies the hybrid configuration process
- The error handling experience allows for simple remediation of issues, meaning you can actually read and understand the error
- Fixes for HCW can happen quickly and are no longer tied to the on-premises product release cycle
- Inefficient code that caused the HCW to take hours to run has been completely reworked and now you should be in and out in minutes
- Many more enhancements explained in our previous blog post
