Hi

infrastructure that I have is:

2 ADs (DomainA.local & DomainB.local) In the DomainA.local I have an Exchange 2007 (8.0.535.0) and the DomainB allcomputers with email account.
The problem is that it is giving me the following error: Your Out of Office settings cannot be displayed, because the server is currently unavailable. Try again later.
It occurs to me both with Outlook 2007 & 2010.

That solution can have?

Regards

Hello

Check autodiscover url
right klick to outlook icon with ctrl and automatic email conf test...
and start test and check autodiscover message.

Hi,

The autodiscover fails me.

The problem is that I have it set so that it detects the internal server but never done that check, always the external. How do I force the internal connection?

Check the solution. https://support.microsoft.com/en-us/kb/2596516?wa=wsignin1.0

Hi

I tried also in the Outlook 2010 and it does not work.  :(

Hi all

I have recreated the VDs and it keeps giving error. If the host of the conputer put autodiscover.public-domain.com works and detects the internal server.

Is it possible that the autodicover look for public-domain.com/autodicover,autodiscover.public-domain.com and server-internal.ad-domain.local?

Regards

It searches for autodiscover.emaildomain.com (e.g. autodiscover.contoso.com)
If you ping autodiscover.emaildomain.com it should return your internal server IP.

Can you try out of office from external network (i.e. from internet)?
if it works from external network you will have to check your IIS bindings

Hi MAS

The autodicover.externaldomain.es ping is correct, but I do not want is to resolve that domain, but directly the internal server. Is this possible?

I guess you have splitdns or pinpoint DNS configured in your internal DNS server.
If not please check my article above.  It is explained.

Your ping of autodiscover.emaildoamin.com should return your internal server IP (e.g 192.168.0.101)

Hi MAS

The problem is that I can create on my internal DNS area external-domain. Is that what you mean?

Hello

please share same picture from client and
output: Get-AutodiscoverVirtualDirectory |fl *url*

@ThorEIPoderoso  You have to create externaldomain.com forward lookup zone and create an a record "autodiscover".   As requested please post the resulting screenshot

Get-AutodiscoverVirtualDirectory |fl *url*
-------------------------------------------
InternalUrl : https://server-internal.ad-domain.local/autodiscover/autodiscover.xml
ExternalUrl : https://autodiscover.autodiscover.public-domain.com/autodiscover/autodiscover.xml

Test Outlook
--------------------------
SMTP=user@public-domain.com
Autodiscover to https://public-domain.com/autodiscover/autodiscover.xml starting
GetLastError:12029; httpStatus=0
Autodiscover to https://public-domain.com/autodiscover/autodiscover.xml FAILED (0x800C8203)

Autodiscover to https://autodiscover.public-domain.com/autodiscover/autodiscover.xml FAILED (0x800C8203)

Why not search in https://server-internal.ad-domain.local/autodiscover/autodiscover.xml??

Hi MAS

I have that record given high in the ISP but then it gives error in TMG and not solve by the certificate. It is not possible that instead of looking for the autodiscovery in the external-domain search for it internally?

Hello

The two domain have a domain trust? or one forest?
if computer in remote domain not acces to domainA AD outlook not reading scp.
the client in domain b need resolved from internal DNS autodiscover.public-domain.com /what is pointing to exch server/ and trust in exchange certificate.

Hi

Both domains have a trust relationship.
The DomainB compuyters, meet autodiscover.public-domain.com but the external IP. I tried to publish the autodiscover.public-domain.com by TMG but I gives an error that I cannot solve: Error details: 0x80090322 - The target principal name is incorrect.
The DomainB Manager will not let me create the area of the autodiscover.public-domain.com

Hello

on tmg published  cert check for all name is available.

with Export-AutoDiscoverConfig you can publishing scp in domainb

or add client custom xml for autodiscovery
