EAC is web-based management console in Exchange 2013 which is replaced EMC in Exchange 2010. The MMC base console used to be slow when it loads and new business logic in Exchange 2013 forced to have new EAC in my opinion. Most of us, most often appreciate new futures and try to adapt them as quick as possible. When certain things are done in certain way over years and people get used to it, it could be bit disappointment to some of you out there to see brad new management interface.
So my recommendation is, forget about GUI if you are going to stay in Exchange Server business (-: , learn and use PowerShell and who knows next version we might not even get EAC (-: , pure PS to manage next generation of Exchange Server.
To get to EAC this is what you have to insert into your browser ( from your CAS Server or replace the local host with CAS Server FQDN or IP Address)
Now this will give you EAC
If you are in Co-existence with Exchange 2010 , same URL wont work for you , so need to use this one
ECP= Exchange 2013
ECP= Exchange 2010
Now if you miss old console and keep cursing things as you get used to EMC here is a nice trick might be able to lessen your pain (-: , yehh I hear you….
Create custom MMC , see the video , I have also added ADUC and ADSIEDIT into my console. I wish at the least MMC console was bit more flexible to do more with it.
