Correct path in SharedWebConfig.config for ClientAccess

Hi KosmosKami,

the extra \ character in the path before \bin is a typo. The correct path to the SharedWebConfig.config file is:

C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\SharedWebConfig.config

To fix the path in the SharedWebConfig.config file, you can use a text editor such as Notepad to open the file and remove the extra \ character. Once you have saved the file, you should restart the Exchange services.

Yes, the missing SharedWebConfig.config file is likely related to the non-working OWA. To create the SharedWebConfig.config file again, you can use the following command:

DependentAssemblyGenerator.exe -exchangePath "%ExchangeInstallPath%\bin" -exchangePath "%ExchangeInstallPath%\ClientAccess" -configFile "%ExchangeInstallPath%\ClientAccess\SharedWebConfig.config"

Once you have created the SharedWebConfig.config file, you should restart the Exchange services.

Here are the steps to fix the non-working OWA:

1. Open a command prompt window as an administrator.
2. Navigate to the Exchange installation directory.
3. Run the following command:

DependentAssemblyGenerator.exe -exchangePath "%ExchangeInstallPath%\bin" -exchangePath "%ExchangeInstallPath%\ClientAccess" -configFile "%ExchangeInstallPath%\ClientAccess\SharedWebConfig.config"

1. Restart the Exchange services.

Once you have completed these steps, OWA should be working again.
