Forward Mail From Exchange (On-Prem) To Office 365
KB ID 0001467 Problem WARNING: Do not do this, if you are carrying out a Hybrid migration to Office 365! I’ve been doing an On-Prem to Office 365 migration recently. It was a little unusual because the ‘on-prem’ Exchange was not in the clients domain.
