Marc Gehri Hey Marc how did you get on with this one? 

I notice these questions get more of a response when posting on docs.microsoft.com forums as opposed to these techcommunity ones.

 

I am interested to know how you got on with this though, as I am implementing something similar with one of my customers.

 

I'm interested to know your thinking around migrating them to your local on-prem first and then into O365.. because I'm thinking that if you (will) have a trust in-place, then you could migrate them to O365 from the existing Exchange environment (set up Hybrid) and then you can use Set-MsolUser scripts to force the immurable ID of the MSOL User objects for them O365 mailboxes to use the on-prem AD account in your target environment that you have set up via AADConnect being the source of authority?

 

Just thinking out loud with you.

 

Thanks

Ron.
