Incomplete sync of Exchange Message Moderation settings to Office 365 / Exchange Online
We setup message moderation for some of our distribution lists. We still have an Exchange 2010 server in hybrid with no mailboxes on premise that via AD Connect goes to Office 365 / Exchange Online. I have an odd problem that message moderation settings don't flow fully from local to cloud. I am able to edit it in cloud even though it is synchronized group luckily but not sure why it is happening?
Reading here the msExchBypassModerationLink attributed has been supported by AADConnect since version 1.1.524.0
So it appears to be a bug where Azure AD isn't anchoring the attribute to only be controlled by on-premises.

I'm not at home currently so I cannot check this in my lab, however according to the documentation, the corresponding AD attributes should be synchronized to Exchange Online (https://docs.microsoft.com/en-us/azure/active-directory/hybrid/reference-connect-sync-attributes-synchronized).
Two things come to mind: check whether there are modifications made to the default sync rules, and check whether the users/groups that are configured as moderators are in the scope of sync.

That group in question is definitely in scope of sync and I can manually add it. The other interesting thing is I can't enable message moderation for O365 side since it is AD based group, that must be synchronized. However once I enable it I can then edit properties only on O365 side?
Like Vasil says, check the attributes are in the scope of sync. They should be but maybe someone has edited the synchronisation rules.
The only other thing I might ask is what is the version of the directory synchronisation tool? Having a quick look I cannot see a bug for moderation attributes but if it is old it would make sense to update it.

I was on 1.1.880 from August. I just installed 1.2.68 and will test again.
