Study this article if you can’t access Exchange Server 2019 ECP(Exchange Control Panel) or OWA(Outlook Web Access).
In your Exchange Server Infrastructure, if your ECP/OWA
console doesn’t open and you encounter EventID:1309
in the Application Log, the root cause of the problem is the missing SharedWebConfig file.
You can see this in the “Application Virtual Path” – “Application Path” in Event ID 1309
.
To resolve this issue follow these steps:
- Access the server with the problem.
- Generate the missing file:
- Run cd
%ExchangeInstallPath%\bin
to change the current directory to the bin folder that’s under the Exchange installation path. - Use the
DependentAssemblyGenerator.exe
tool - If the file is missing from
C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy
, run the following command:DependentAssemblyGenerator.exe -exchangePath "%ExchangeInstallPath%\bin" -exchangePath "%ExchangeInstallPath%\FrontEnd\HttpProxy" -configFile "%ExchangeInstallPath%\FrontEnd\HttpProxy\SharedWebConfig.config"
- Run cd
IISReset
You can now access ECP!
P.S
: If you encounter EventID:1309
, carefully check its contents.
Because in the problem I mentioned above, the issue was related to the ECP.
EventID contents; “Application Virtual Path: /ecp
” and “Application Path: C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\ecp
“
If these contents are as follows;
Application Virtual Path: /owa
Application Path: C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\owa\
To resolve this issue follow these steps:
- Access the server with the problem.
- Generate the missing file:
- Run cd
%ExchangeInstallPath%\bin
to change the current directory to the bin folder that’s under the Exchange installation path. - Use the
DependentAssemblyGenerator.exe
tool - If the file is missing from
C:\Program Files\Microsoft\Exchange Server\V15\
ClientAccess, run the following command:DependentAssemblyGenerator.exe -exchangePath "%ExchangeInstallPath%\bin" -exchangePath "%ExchangeInstallPath%\ClientAccess" -configFile "%ExchangeInstallPath%\ClientAccess\SharedWebConfig.config"
- Run cd
IISReset
You can now access OWA!
Have a nice day !
