    One more thing. All the preps are done and I am about to install Exchange 2016 on this machine now. Just to be cautious; are there any things that might influence the current Ex2010/EOL Hybrid environment or traffic? Just to be sure I have retrieved the current autodiscover settings and created a little script to re-set the autodiscover settings back to their original values, just in case they might be adjusted.

    Thanks again!

      Be sure to establish mail flow in your new environment prior decomissiong Exchange 2010 hybrid. Or queue the mails from on-premises <-> EXO during the time you configure the new hybrid organization.

        Thanks. I sure will. Just for now, the basis installation, so prior to run the setup.exe now, I was wondering if anything else can be 'broken'. I can't think of any, since these are two complete different forests (they do have a trust of course).

         

        Configure mailflow, new hybrid etc. will be done later.
