Hi
I am migrating from ex2007 to ex2013 and users on ex2007 cannot access OWA via thehttps://mobile/owa but can access OWA via https://legacy/owa. The legacy users get an 500 error when using mobile/owa. Ex2013 can access OWA usinghttps://mobile/owa just fine
It appears that exchange 2013 is not redirecting to the legacy mailboxes.
I have created internal and external DNS records that point to the legacy email server
I have created a tmg publishing rule for the legacy host name
I have configured DNS records that point mobile.contoso.com to the new exchange 2013 server
I have configured OWA on the exchange 2007 OW virtual directory with the namespace legacy.contoso.com/owa
Can anyone tell what else I can check?
I have posted question on other resources as I running short of ideas
Cheers
