Resource Forest, Account Forest - Exchange Removal questions.
Hey Guys, This is a strange one i have never come across before so please assist if you can. At this time i want to better understand what needs to be done to remove the Resource Forest (de-coup...
BrianDesmond Thanks again.
To be clear for myself on this process, and to make sure i have the order right, with all mailboxes already migrated to office 365, I should do the following:
- Install Exchange in the Account Forest, creating a new exchange org.
- Copy MSExchange Attributes over, I will work to copy the correct ones over as i know not all need to be copied. Account should show as "office 365" mailbox in EAC in the account forest, and should show as "RemoteUserMailbox" when checking in EMS.
- Uninstall Exchange from the Resource Forest
Is that about right? I will of course test everything in my lab, before making any changes on the customers environment, and may reach out to PFE for a design review to be doubly sure.
The customer also needs to migrate all their groups to office 365 as well, however for that i think the correct course of action is to create a script (or find one) that simply creates the groups in the cloud, re-assigns all group memberships and send as, send on behalf of settings, and group security settings.
The group portion would probably need to be done first, I would imagine.
Thanks again!!

Robert Bollinger did you get this working? I have exactly the same scenario and just wanted to check if those steps worked or if you found out anything else that needs to be considered?
- I think this is pretty well documented here
