exchange decomissioning
Hello some qeustion,
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 ,
my question is, remove from ad will be have impact to use this exchange online ? remove from configuration with adsi edit , or from naming contest, maybe some settings are modified for this exchange online ?
and restoring exchange items ( mails ) from veeam backup, if removed exchange 2016 from ad, is working or need for recovering exchange settings in ad ?
- Dan_SnapeSteel ContributorAre you using Entra Connect to sync your on-premises AD to Entra ID? If so there's a process to follow before you can "decomm" on-premises Exchange. The first issue you have is that it only works for Exchange Server 2019.
