  1. Hi Satheshwaran Manoharan,

    Hope you’re doing great. I have a quick question regarding the deoployment of Exchange 2013. I would like to do a clean install first time installation of Exchange 2013 in my test environment. In what sequence shall i install the server roles? should i install first CAS server role and then Mailbox server role or first Mailbox server role and then CAS server roles. Does it matter which role installed first. Please let me know.


  2. Hi Satheshwaran Manoharan,

    Hope you had a nice weekend. Thanks for your quick resposne to my question. However I tried installing first CAS server before installing the mailbox role, it is not working. I completed the prerequisits and readiness checks etc. the CAS server installation remain incomplete and as a result of this i was not able to use EMS and Exchange Administration Center (EAC), I contacted MS support and they asked me to try first installing mailbox server role and then try intalling CAS server role. I am wonering is this a requirement or just a recommandation? I do appreciate your input in this regard.
