Hi ,

User is facing the below error while login the mail through outlook ( RPC over http).

"There is a problem with the proxy security certificate.

Outlook is unable to connect to the Proxy server

webmail.abc.com ( error code 20)"

There is no problem with webmail access.

while I checking the certificate, it is showing IIS certificate invaild ( it is expired).

So I Renew the certificate by the new-exchange certifcate command , but still same problem.

We are not using any external trusted certificate, is there any possibility to expired any SAN CA certifcate, so , please suggest how do in created SAN root ( CA ) certificate & export in two CAS serevr which are in LNB.

We are using Windows Server 2008 NLB for cas Server.

It is urgent , please suggest.

I assume that u have used
Get- ExchangeCertificate -Thumbprint '01234567890123456789' | New-ExchangeCertificate
Have you restarted the MSExchangeTransport Service ??

Here are the commands needed to renew a self signed cert.  

1 Get-ExchangeCertificate -domain "domain" | fl
2 Get-ExchangeCertificate -thumbprint "2FB28F5075EFE9B30A8F8458DED0A191542HUG6J" | New-ExchangeCertificate
3 Confirm Overwrite existing default SMTP certificate
4 Enable-ExchangeCertificate -thumbprint "FB5AECA6B39816F02B3245BD1D95394458741HU7" -services IIS

If you've done these already then you probably just need to restart iis, at a command prompt type iisreset.

I have already done the same, it is problem with SAN certificate.

Please let me know why we required self SAN certificate even though we are generating a new exchange certificate through the command prompt.

Please create a new self signed SAN certificate as it has entry for autodiscover.domain.com which is required for RPC over https.

Also make sure we have proper certificate for NLB url in IIS manager

The problem was self SAN certificate. After create the certificate, submitted to local CA server then enable the certificate in both the Hub Transport Server.
