fresh installation of Exchange 2013 with SP1 on Windows 2012 R2. basic configuration.
test-servicehealth results = all services are up and running
test-mailflow results = *FAILURE*
Created 3 mailboxes / sending e-mails internally stuck in drafts... as per some blogs on this problem, they proposed to fix the DNS on ECP and some GPO updates for "access to this computer from network" all are updated but still same problem!
Stuck with this problem since 2 weeks and I couldn't find any fix yet.
Any help is highly appreciated.
