Hi Experts,

I have installed Exchange 2013 with co-exist Exchange 2010. All the migration has been almost done.

Exchange 2010 has: webmail.mydomain.com

Exchange 2013 has: owa.mydomain.com

I have set autodiscover point to new exchange, all mails incoming and outgoing are fine.

However, the new exchange has been configure with a new purchase certificate and it shows status INVALID, I have found out that is because of the certificate itself problem and decided to export the exchange 2010 certificate (still valid) and import to new exchange 2013. The import is fine, I got the status VALID.

But now I have problem can not connect to Exchange 2013 mailbox when I launch MS outlook, it keep asking me for credential, and I am stuck here.

I tried on some machine and first of all they can launch MS outlook and connected to exchange but there is an error said problem with proxy setting.

I open Microsoft Exchange Proxy setting and I am very confused that it keep connecting to owa.mydomain.com  and  msstd:owa.mydomain.com

I think this is the cause of the problem but I don't know how to set or configure in new exchange 2013 to let it forget or delete the old address owa.mydomain.com.

Access to exchange via webmail is fine, no issue. Please help me

Thanks and regards,
phucdk

There are loads of places that you will need to change:

OWA,
EWS,
Autodiscover,
Outlook Anywhere,
OAB.

I haven't finished the Exchange 2013 version, but the same virtual directories are involved that are listed in my Exchange 2010 article: http://semb.ee/hostnames

The script at the end should work fine for Exchange 2013.

Ensure that you have the DNS correct as well, but internally and externally.

Simon.

Hi Simon,

Well, I did change all of the services that you listed when I switch to the old webmail.domain.com

I have spent 6 hours to troubleshoot until I tried to log in domain with a test user and Voila! it just works. Just let you know that day I was troubleshooting by using a non domain users and manual configure outlook with a domain user (what ever I do, it keeps promting for pwd)

Anyway, the problem solved. I have tried to login my own domain user account, launch outlook, then I get out of domain in a local machine, tried o manual configure my email account with outlook again and this time it works.

I think because there is old (setting or pst ?? files ) so that\s why it did not work from the first time.Anyway, thank you Simon.

Regards,
phucdk
