OK I guess option 2 is a valid option. a old blog: https://techcommunity.microsoft.com/t5/exchange-team-blog/decommissioning-your-exchange-2010-servers-in-a-hybrid/ba-p/597185
"in many cases an Exchange 2010 server can simply be added back to the organization to simplify the management process. These organizations will need to ensure that a mail-enabled user is in place for all Exchange Online mailboxes in order to properly configure the mailboxes"
So a mail-enabled user ( mailuser ) is the proper configuration.

- VasilMichevMar 15, 2022MVPYou don't need the HCW/Hybrid config. And the only reason you need an Exchange management box is because that's the only *supported* way to manage Exchange-related objects and attributes. Technically, you can manage them just fine with the AD tools, as long as you have the Exchange schema extensions. But even though this is technically possible, it's not considered a supported scenario, thus Microsoft advises against it.
- Jack_Chen1780Mar 15, 2022Brass ContributorThanks Vasil, yes I understand the purpose for the on-premises is for management, just wasn't sure what is the supported way to create new mailboxes without HCW ( can't create office365 mailbox from on-premises Exchange without HCW).
Now based on the Microsoft blog, I think mailuser is the way to go.- VasilMichevMar 15, 2022MVPSince you will need to manage all the attributes on-premises, mail user is preferred yes.
