Autodiscovery outlook 2016 not working for secondary domain on exchange 2010 sp3 SBS2011.
setup:
SBS2011, exchange 2010 with sp3.
internal domain: domain1.local
external domain: domain1.eu
external dns a records
remote.domain1.eu external ip (godady certificate is on this one)
mail.domain1.eu external ip
autodiscover.domain1.eu external ip
configuring outlook 2016 with just email address and password works fine.
Now there is a second domain on the same box where autoconfigure does not work all the time
It hangs ons searching email server settings right after a certificate error (which is understandable cause it belong the domain above)
external dns a records
remote.domain2.eu external ip (godady certificate is on this one)
mail.domain2.eu external ip
autodiscover.domain2.eu external ip
After writing this question and leaving the search open after 15 minutes plus I do het a user name password question and outlook is configured.
Strange! help much appreciated!
Thanks, Tom.

Hello Texas!! Thanks for helping out!
the nslookup for test.domain2.eu fails
nslookup domain2.eu comes back with domain registrars IP

Ok I'm trying to establish if there is a wildcard DNS entry which can cause issues for Autodiscover. When you say it returns the registrar IP, do you mean the A record query for test.domain2.eu was able to resolve a WAN IP?
What about the ExRCA test?
What about the ExRCA test?
Oh sorry, It did not upload.
It is not resolving to the correct wanIP where exchange is listening.
I think that is the wildc
But neither is domain1.eu
I changed the record domain2.eu from the hoster to the external ip the exchange server is listening on.
I'll let you know. Have leave the house in a little bit so please give me some time.
THank you so far! Tom.

Hi Jason,
That was it. The discovery works fine now. Thank you for you help. I am just wondering if there were records I was missing. Any idea?
Thanks again! Tom

Generally you need at least two:
Type: A
Host: mail.domain.com
Value: <Insert WAN IP>
Type: CNAME
Host: autodiscover.domain.com
Value: mail.domain.com
Optional:
pop.domain.com
smtp.domain.com
imap.domain.com
You can technically get by with one and avoid the extra expense of a SAN certificate, but for simplicity sake just ensure at a minimum you have mail and autodiscover.
