Correct path in SharedWebConfig.config for ClientAccess

Copper Contributor

Hello, community.

After installing the next update, I received a non-working OWA. As you may know, Microsoft recommends that you create the file SharedWebConfig.config in ClientAccess folder again using the utility DependentAssemblyGenerator.exe. But, when command

 

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

 

done, I got the next  I am getting the following content in the file

 

<codeBase version="4.2.0.0" href="file:///C:\Program Files\Microsoft\Exchange Server\V15\\bin\AntiXssLibrary.dll" />

 

or

 

<codeBase version="1.1.5274.28150" href="file:///C:\Program Files\Microsoft\Exchange Server\V15\\bin\AsyncDnsManaged.dll" />

 

So I have a question. Why does there appear another \ character in the path before \bin?

And when I check the server status with script from PSGallery, one of the items is that the file SharedWEbConfig.config is missing. Could this be related?

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.

Thank you.
I have a couple more questions. I tried to delete the file and the utility creates it itself with the wrong syntax. It's strange, isn't it? I don't think there's much point in trying it again. I'll try to edit the file in Notepad. And one moment. Need to restart all Exchange services? In the microsoft article it was stated that it is enough to perform iisreset.
