Hi!
I am replacing our current pop mail server to Microsoft Exchange Server 2013. I installed it on a trial/test windows 2012 R2 Server. I have encountered some errors like the machine wasn't part of the domain, IIS and etc. like 20 errors in total but I got past that from the guide I've found online and I can access the EAC and manage the Exchange server. When i did a test on a new user I created, it didn't work like no send and receive at all so I went to Mail Flow and configured the Send Connector which internally it works but I can't receive any email which when I checked the Receive Connector there was a presetup stuff on it already which I'm assuming that it would work/correct. So the problem as far as I'm concern was, I can't send out any emails (internal/external) and for some whatever reason sometimes even the internal is not...
