Hello,
our customer has primary domain (primary.com) with Exchange 2016 Hybrid.
Later they bought a new domain (secondary.com), added to O365 and configured some mailboxes wih @secondary.com domain. These are cloud-only mailboxes. This domain is not added to onprem Exchange accepted domain.
Is there any risk if I add this secondary.com domain to onprem Exchange accepted domain? (for example, existing cloud-only mailboxes will be deleted or something problematic thing?)
Thank you,
Zoltan
