Hello.
We are recently migrated from Exchange 2010 to 2013 CU8. All roles are installed on one server.
Most of our users connecting to Exchange from external networks with Outlook 2013 and they get this autodiscover.xml (seehttp://pastebin.com/LWaDYDUy).
Here virtual directory config:
get-AutodiscoverVirtualDirectory | fl identity,internalurl, externalurl Identity : EXCH02\Autodiscover (Default Web Site) InternalUrl : ExternalUrl : get-ClientAccessServer | fl identity,AutodiscoverServiceInternalUri Identity : EXCH02 AutoDiscoverServiceInternalUri : https://exch02.company.local/autodiscover/autodiscover.xml get-webservicesvirtualdirectory | fl identity,internalurl,externalurl Identity : EXCH02\EWS (Default Web Site) InternalUrl : https://exch02.company.local/EWS/Exchange.asmx ExternalUrl : https://mail.company.com/EWS/Exchange.asmx get-oabvirtualdirectory | fl identity,internalurl,externalurl Identity : EXCH02\OAB (Default Web Site) InternalUrl : https://exch02.company.local/OaB ExternalUrl : https://mail.company.com/OAB get-owavirtualdirectory | fl identity,internalurl,externalurl Identity : EXCH02\owa (Default Web Site) InternalUrl : https://exch02.company.local/owa ExternalUrl : https://mail.company.com/owa get-ecpvirtualdirectory | fl identity,internalurl,externalurl Identity : EXCH02\ecp (Default Web Site) InternalUrl : https://exch02.company.local/ecp ExternalUrl : https://mail.company.com/ecp get-ActiveSyncVirtualDirectory | fl identity,internalurl,externalurl Identity : EXCH02\Microsoft-Server-ActiveSync (Default Web Site) InternalUrl : https://exch02.company.local/Microsoft-Server-ActiveSync ExternalUrl : https://mail.company.com/Microsoft-Server-ActiveSync
We are using certificate from domain CA with SAN:
DNS name=mail.company.com
DNS name=exch02.company.local
DNS name=autodiscover.company.com
DBS name=company.com
All working fine except one thing: Outlook 2013 from external network trying to download OAB from internal url. Here is output from "bitsadmin /list /verbose":

After a hour BITS will cancel this job and download OAB from external URL without any problem. But if i restart Outlook - it will again use internal URL.
Any ideas?
