Decommission Exchange Server after Migration to Office 365
After a successful Migration from OnPrem Exchange Server to Office 365 via Hybrid Scenario O365 Support answered that I have to leave the Exchange Server in my Environment.
No Customer wants to handle a not anymore used Exchange Server in they're Environment, specially with a view into future, shell we always leave a Exchange Server 2010 running for 10 years?
There need to be a way provided from Microsoft for probably ten-thousands of customer to remove Exchange Server and still leave AAD Synch in Place! (most customer want to have only one Identity for their Users (in Active Directory)
I would like to recommend Kernel Migrator for Exchange software. It can help in Exchange to office 365 migration, Office 365 migration, Exchange to Exchange migration, etc. For more information, visit: https://www.nucleustechnologies.com/blog/migrate-from-live-exchange-server-to-office365/

Correct . When the mailboxes are migrated it should NOT require on prem exchange servers in order to maintain the mailboxes etc. We had a Lotus notes shop and migrated but still have AD accts. The supported method for us to do this is to have on prem Exchange servers. Seems pretty much a waste of resources to me.. It's 2018 and that is still the recommended procedure??

Just got off the phone support and they actually recommend we keep our local exchange server for now rather than getting us a third party tool that they will not support. So please microsoft make us a tool or wizard that allows decommisionig of an old local exchange server.
I agree. Following a succesfull migration to Office 365 we do not want to maintain a local Exchange server regardless of how little it does. There needs to be a way that this piece can be removed or the requirements be seperated into a seperate package (such as AD schema and management shell) without requiring Exchange to be installed.
