Replacing CAS, autodiscovery

Question

Hello!
The situation is following:
1) installed MAILCAS.example.com with MBX and CAS roles. Created AUTODISCOVER.example.com (cname to MAILCAS) in public DNS servers.
2) installed MAIL.example.com with CAS role.
3) installed MBX1 and MBX2 with MBX role and created DAG.
4) moved mailboxes from MAILCAS to DAG.
5) changed AUTODISCOVER.example.com to point to MAIL.example.com
5) Now I want to remove server MAILCAS. Problem is that I get unwanted information from autodiscovery. There are still instructions to MAILCAS.
I used Connectivity Analyzer. Exchange Web services connectivity test (service account access) says
this.
Autodiscover and Exchange ActiveSync test says
this. Outlook Autodiscover test says
this.
In Exchange Management Shell:
[PS] > Get-ActiveSyncVirtualDirectory | ft -autosize
Name                                          
Server InternalUrl
Microsoft-Server-ActiveSync (Default Web Site) mailcas   https://mailcas.example.com/Microsoft-Server-ActiveSync
Microsoft-Server-ActiveSync (Default Web Site) MAIL   https://mail.example.com/Microsoft-Server-ActiveSync
[PS] > Get-OabVirtualDirectory | ft -autosize
Server Name                   Internal Url              External Url
mailcas   OAB (Default Web Site) https://mailcas.example.com/OAB https://mailcas.example.com/OAB
MAIL   OAB (Default Web Site) https://mail.example.com/OAB https://mail.example.com/OAB
[PS] > Get-OwaVirtualDirectory | ft server,name,internalurl,externalurl
Server                        Name                         
InternalUrl                   ExternalUrl
mailcas                       owa (Default Web Site)        https://mailcas.example.com/owa    
https://mailcas.example.com/owa
MAIL                          owa (Default Web Site)        https://mail.example.com/owa    
https://mail.example.com/owa
[PS] > Get-WebServicesVirtualDirectory | ft server,name,internalurl,externalurl
Server                        Name                         
InternalUrl                   ExternalUrl
mailcas                       EWS (Default Web Site)        https://mailcas.example.com/ews/... https://mailcas.example.com/ews/...
MAIL                          EWS (Default Web Site)        https://mail.example.com/EWS/... https://mail.example.com/EWS/...
I really don't have idea where comes the information from MAILCAS. What did I forget?

Hi Lote,
Guess you missed Setting the AutoDiscoverServiceInternalUri on the new server.
Also check if Active Directory is populated with correct SCP (using ADSI).
Example below:
Set-ClientAccessServer -Identity "CAS-01" -AutoDiscoverServiceInternalUri "https://cas01.contoso.com/autodiscover/autodiscover.xml" -AutoDiscoverSiteScope "Mail"

You might also want to wait 48hrs, as changes to the Public DNS and user cache would take some time to flush.
