HiAccording to Microsoft this is not a supported scenario. When using ADconnect there should be an instance of Exchange running On-Premises. There are a free Hybrid license for Exchange 2016 also, if no mailboxes live onpremises.To read more about this and different scenarios, please read here:https://techcommunity.microsoft.com/t5/exchange-team-blog/best-practices-when-decommissioning-exchange-2010/ba-p/1247559https://docs.microsoft.com/sv-se/exchange/decommission-on-premises-exchange?redirectedfrom=MSDNAlthough, many DO remove all servers even in this scenario. It’s up to your org to decide here. To remove exchange totally there’s plenty of guides step by step onlineAdam
