I am using Hybrid Azure AD and Entra ID with Password Hash Sync, all objects are synchronized using the Azure AD Connect software.

There are 2x Exchange Server 2016 but both have no mailboxes on-premise only used for managing the AD attributes as I cannot decommission it

Is the below check box required for me to enable or not?

    Hello EnterpriseArchitect,

    Thanks for your question.

    With your description that there is no sync of anything from exchange on-prem, If there is no need for any mail sync, you do not need to enable this. However pls note the synced attributes here for exchange:

    https://learn.microsoft.com/en-us/entra/identity/hybrid/connect/reference-connect-sync-attributes-synchronized#exchange-online

    As well as those written back:

    https://learn.microsoft.com/en-us/entra/identity/hybrid/connect/reference-connect-sync-attributes-synchronized#exchange-hybrid-writeback

    These can further assist in determining your use case for this.

    Please let me know if you have further questions
