Hi
I have a 2Exchange Server MBX AND MBX1 is apart of DAG, which external connection point of acceptance is CAS1.
I Studied a lot of articles but i am facing some issue of Autodiscover connectivity from outside ,
I have to configure Autodiscover(Default Web Site) Internal and External URL in virtual Directory through GUI or PowerShell should i use or i don't need to configure this Autodiscover default website and leave it blank or what.?
But when i run command on CAS1>Get-AutodiscoverAccess Server | fl i am getting internal url like https://mail.mydomain.com if its exist in cas1 than why in ECP>server>virtual directory is not showing the internal url on ECP gui ?
You dont configure the autodiscover virtual directory URL. You set the other clients URLs for external access:

If you notice, it only apples to Exchange 2010 to set that:

my all other urls are exist of ECP\OWA\EWS\OAB\ACTIV-SYCN etc but as shown in pic Autodiscover (Default Web site) is missing. So according to you it should be remain as it's or blank?
Should be blank for the internalURL for the AutoDiscovery Virtual Dir
in 2016 and 2019, there is a bug that requires filling out the externalURL
i am following your provided articles.
but i am using exchange 2013,so can you clear that Autodiscover default website url is to be filled?
because you are saying it should be 2016 and 2019 have a bug that's why to be filled in them.but in my case i have a 2013 and externalurl is blank
In that case, both internal and external URLS should be blank
ok got it.
moreover can you check my attached screenshot of Test connectivity analyzer error ? and after that any suggestion ?
Is the server accessible from the outside? Note, its not supported if that server is in the DMZ
Sorry did not got you point? Can you make it clear?.in what case you are asking is server accessible from outside ?
CAS1 is live its cas1.abc.com A record exist globally and it accept the outlook request or you can say its on the front end for connectivity via owa but not work outlook autodiscover\autodiscover.xml
autodisocover.abc.com its A record already exist and resolvable .
Are firewall ports open to the CAS server from the outside on port 443?
Is this server in the DMZ or internal LAN?
**1.I am able to telnet from outside like **mail.abc.com, cas1.abc.com, autodisocvere.abc.com 443 ports are telnetable.****
2.i am not sure but i think the server is in a DMZ.
It is an expected behavior that there doesn't show external user for Autodiscover from the ECP(It doesn't mean this value is null):
You could use command below to check ExternalUrl from EMS (Don't need to care about the value of InternalUrl):
Get-AutodiscoverVirtualDirectory -server exch | fl name, *url*
If there exist issue with your Autodiscover connectivity from outside, you could use the MRCA tool to check whether there real exist issue with External Autodiscover.
You can also from an external client to use "Test Email Autoconfiguration" check whether there exist issue with external Autodiscover:

as i said that all other url exists except autodisocver (Defualt Website Sitet)
my all other urls are exist of ECP\OWA\EWS\OAB\ACTIV-SYCN etc but as shown in pic Autodiscover (Default Web site) is missing. So according to you it should be remain as it's or blank?

after run a command on my cas1 server below are the output. Please check and assist
Get-AutodiscoverVirtualDirectory -server cas1 | fl name, url
Autodiscover URL doesn't show from ECP by default.
About external URL from EMS, you could follow the article that provided by AndyDavid to set it.
Then, I would suggest you from an external(Out of your domain) computer to use Outlook function "Test Email Autoconfiguration" to check the Autodiscover again.
that's what i am saying is it mandatory to configure the external url for Autodiscover ?
Get-AutodiscoverVirtualDirectory -Server YourExchangeServerName |set-AutodiscoverVirtualDirectory -ExternalUrl https://autodiscover.FQDN/Autodiscover/Autodiscover.xml
?
You need to set this value, I also suggest you use "Test Email Autoconfiguration" to double check the Autodiscover. Because, sometimes there may exist issue with the RCA tool.
iits working with domain joined user but not non domain joined user able to find autodiscover settings.thats the issue
Until the CAS is removed from the DMZ and installed in the internal LAN, we really cant help make this work.
CAS is accessible via internet and i can telnet from anywhere.than why its to be removed from dmz.
Which step failed for "Test Email Autoconfiguration"? You could see lookup steps under "log" label.
Ok, that wont work if so. And its not supported. Only the Edge role can be in a DMZ
CAS1 is connected to DMZ.
If cas1 forward request to dmz and dmz look its a valid traffic so much accept it in my case we have NAT.
It was working before in a same way
But not supported :)
