I am trying to set up Exchange Online Protection (EOP) in standalone mode, meaning it is just filtering spam and malware before passing the mail on to our on-prem mail servers (Exchange 2007).
I can't seem to find a way to add email aliases (ie nate@domain.com and nate.it@domain.com are one user mailbox in our on-prem Exchange server and I want them to be one user in EOP).
Does anybody know how to setup email aliases in EOP?
NOTE: I found some documentation for FOPE, but it seems to have changed since then.
