add new email domain exchange 2010

    Question

  • We running Exchange 2010 SP2 as adumdum.com and now we have acquired kuntusu.com.

    out internal AD domain name is also adumdum.com

    MX points to us, Accepted domain kuntusu.com is added and also set the email policy.  We want this to be the new email policy/ set as default. 

    question ....

    I know I have to get a new UCC certificate.  Should I keep the exisiting names on my certificate and add this new name on the cert?  How do I get this going ...

    thanks!

    So your testing was done on a LAN?
     
    Your browser won't complain as long as the FQDN in the URL matches a
    name in the certificate.
     
    I don't think Outlook will complain as long as it's using SCPs to do
    AutoDiscover.
     
    If you put the Outlook client outside your LAN then AutoDiscover on
    the client is going to use the domain name from the user's primary
    SMTP address to find names in DNS. If it can't find the server it
    isn't going to use AutoDiscover and it'll use what's already in the
    profile.

    If you're assigning kuntusu.com as a primary SMTP address you'll need
    a name in your cert for autodiscover to work for everyone.
     
    Until you've removed all the primary SMTP addresses that are in the
    adumdum.com you'll need whatever you have now to remain.

  • thanks Rich.

    I added the new domain kuntuso.com as accepted domain, cerated the email address policy and set it as default/primary. 

    The cert has the following names ...

    server.adumdum.com, mail.adumdum.com, autodiscover.adumadum.com

    I did a test in my lab where all the roles are on the same server ... and configured the scenario as stated above and it works fine no certificate errors via Outlook or OWA?????

    I will leave all the smtp addresses as is not removing them.

    any ideas?

  • thanks Rich ...

    Yes I am doing the test in LAN and all our pcs in production are in lan and on the domain.... I think i will have no issues.  I am not changing any names on the UCCerts cos the weblink will remain the same.  When we decide to change the domain name then I will recreate a new cert request for OWA.
