I'm about to deploy an new Hybrid Exchange 2013 server for an Office 365 project.
There doesn't seem to be a need that is know that requires external SMTP access, therefore they don't want to use an Edge Transport Role.
If for some reason down the track, it actually turns out that they do need this role, is it something that can be configured down the track? or is it something that really should be deployed at the start?
Thanks again :)
