Hi manuphilip ,

 

Thank you for your continued support.  I am trying the script as suggested and still getting the white screen when opening OWA.  I have attached a screen shot of the powershell screen and the browser screen trying to open owa.

 

Regards,

 

Mark

Hi mark_fad 

It is taking bit more time, as the usual troubleshooting steps didn't help so far. As the certificate swap has introduced this issue, we will check that direction again.

1.  Check eventlog in exchange server and see if you have errors like "An error occurred while using SSL configuration for endpoint 0.0.0.0:444". This will popup immediately after you try to login

2. If this is the case, you have to delete this association by following the steps below in exchange server

  • Open command prompt as administrator
  • Type netsh and enter
  • Type http and enter
  • Again type show sslcert  and enter
  • You will see two entries for 443 and 444. We know that 444 is incorrect and to be deleted
  • Delete by running the command delete sslcert ipport=0.0.0.0:444
  • Add the correct entry add sslcert ipport=0.0.0.0:444 certhash=xxxxxx appid="{yyyyyy}"
  • type show sslcert  and check if you see the entries as correct

3. The above steps should fix the issue.

4. Suppose the above steps are not applicable, forward us the error message from event viewer so that we will further bring up troubleshooting steps

    Hi mark_fad ,

    The interested logs are under Application/System. Try OWA login and check the entries there

    Hi manuphilip ,

     

    Thanks for your continued support.  I went through windows event log and exchange event logs but can not see any errors with SSL in them.  I am not sure if these errors are relevant but i can see the following:

     

    MSExchange Management Logs

    Cmdlet failed. Cmdlet Get-UserPhoto, parameters {Identity=Jordan.Yap@afgroup247.com.au}.

    Cmdlet failed. Cmdlet Get-MailboxDatabaseCopyStatus, parameters {Identity=Mailbox Database 1063958844\*, DomainController=AFSERVER.anytime.local}.

     

    Active Directory Webservice Logs

    Active Directory Web Services could not find a server certificate with the specified certificate name. A certificate is required to use SSL/TLS connections. To use SSL/TLS connections, verify that a valid server authentication certificate from a trusted Certificate Authority (CA) is installed on the machine.

    Certificate name: AFSERVER.anytime.local

     

    Is there any particular log file i should be checking?

     

    Regards,

     

    Mark
