Domain joined machines and outlook pop up shows up with this error

“The name on the security certificate is invalid or does not match the name of the site”

Coz the internal server name is not listed in my cert as recommended

Now Outlook get this pop up while retrieving the Autodiscover information

you got to change this entry to avoid this . so that it will start looking at mail.testcareexchange.biz

Run

Get-ClientAccessServer | fl Identity,*uri*

Now run to set to the entry which is on the cert.

Set-ClientAccessServer -Identity EXCH2013 -AutoDiscoverServiceInternalUri https://mail.testcareexchange.biz/Autodiscover/Autodiscover.xml

Do an IISreset – if changes doesnt take effect.

  Make sure machine is domain joined. It does work only for domain joined machines

Only a quarter of the fix and IISReset does nothing, to actually fix it, enter these THREE commands: NOTE: replace SRVNAME with your servers internal NETBIOS name and YOURURL with the external url that matches you cert (without the )

Set-ClientAccessServer -Identity SVRNAME -AutoDiscoverServiceInternalUri https://YOURURL/Autodiscover/Autodiscover.xml

Set-WebServicesVirtualDirectory -Identity “SVRNAME\EWS (Default Web Site)” -InternalUrl https://YOURURL/ews/exchange.asmx

Set-OABVirtualDirectory -Identity “SVRNAME\oab (Default Web Site)” -InternalUrl https://YOURURL/oab

Open IIS
Goto Application Pools
Right click MSExchangeAutodiscoverAppPool then click Recycle

Your welcome

    Hello guys,
    
    I have ran all the above three command plus the one shown bellow and it has solved my problem. Make sure to change the Thumbprint with the one shown on your valid certificate.
    
    Enable-ExchangeCertificate -Thumbprint F633DA9BFB45D902C0B0CE8A8D4F2EA045D95744 -Services “SMTP
    , IIS”
