Exchange 2010, Update steps with new Primary domain and linked Certificates RRS feed

  • Question

  • Hi,

    I have tried to find this already but cant find much. If I have missed it please link me through.

    Our situation:

    Internal Domain: company.com.au
    Old Mail Domain: companyemail.com.au
    New Mail Domain: newcompanyemail.com.au

    Our company went through a reband. We are at the moment keeping the same internal domain. We have updated the mail domain to use the newcompany.com.au domain. ActiveSync, OWA and alike however are still refering to email.companyemail.com.au

    What are the steps that I need to work through to change this over to email.newcompanyemail.com.au? If it wasnt for ActiveSync I assume this is an easy change. Activesync worries me as if I change the certificate that Exchange uses for IIS will all current clients that access it via the server URL of newcompanyemail.com.au break due to a certificate mismatch?

    We are keeping all old companyemail.com.au DNS entries both public and internal.

    Cheers,



    Zac Avramides
