    Hi Tom,

     

    Option 2 with a few changes to the process

    . Install 2016, setup Exchange 2016, Setup Hybrid, cut mail flow to EOP (Test First), perform the migrations through Exchange 2016 from the 2010 mailboxes, then just tear down 2010 at the end

There is also a 3th option.

Configure Exchange 2010 in Hybrid mode. Then migrate al the users and shared mailboxes to Office 365.

If you have Public folders let them exist in co-existing mode. When the complete migration is done and you public folders are working in Co-existing then upgrade the exchange server which has the hybrid configuration installed to exchange 2016 and you are good to go.

 

Future approaches are: Make the public folders on 2010 read only give users time to move their data over to a shared mailbox or office group. And when all the Public folders are empty decommission the Exchange 2010 servers.
