We have on-premise active directory with exchange 2016 

this exchange server is now down, for mailing we have exchange online, but different domain, nothing with this on-premisse configuration, completely different , user loged with on-premise ad and exchange online

Exchange 2016 is now down, and we are planning decomissioning ,
