Exchange 2013 Error - MapiExceptionUnknownUser: Unable to open message store
This issue was a known issue and It has been fixed by Exchange Server 2013Cumulative Update 1.
I am sure this must help you. You can make fresh install with this cumulative update file or you can install over existing Exchange 2013

I am trying to install Exchange Server 2013 for days. On every try I am getting the error "MapiExceptionUnknownUser: Unable to open message store." while connecting to either ECP or OWA.
In my searches, some people says it is about Reginal Settings. I made a clean install for both Windows Server 2012 and Exchange Server 2013. I have set all reginal settings to English and US. I have installed a server for Active Directory and a seperate server for Exchange. I made everything decent and there was no error at prerequisites. There was no error after installation. But every time I try to reach ECP or OWA I get error about user.
Somebody told me creating a user on AD without mailbox would fix the problem but no.
I could open ECP page by https://< IP >/ecp/?ExchClientVer=15 with ?ExchClientVer=15 This URL doesn't work for OWA.
Could you suggest anything?
