The problem was the path that somehow changes after security updates,To resolve the issue i went to IIS,Exchange Backend website,ECP Virtual directory and select Applications settings,BinseachFolder and remove

"%ExchangeInstallDir%bin;%ExchangeInstallDir%bin\CmdletExtensionAgents;%ExchangeInstallDir%ClientAccess\Owa\bin"

and replace it with the path is complaining about

Hi,

Thanks for contacting our forum. Firstly, please run the Script UpdateCAS.ps1: This script is found under the path: Install path:\Program Files\Microsoft\Exchange Server\V15\Bin

We can also copy the sharedwebconfig.config file from:

Install path:\Program Files\Microsoft\ExchangeServer\V15\FrontEnd\HttpProxy
To:
Install path:\ Program Files\Microsoft\ExchangeServer\V15\ClientAccess

It’s also recommended to refer to the solution in the similar thread:

Hope it helps.

Thanks for your response.

Have you run the script UpdateCAS.ps1? and what’s the results?

It’s recommended to uninstall these two updates and monitor if it’s the root cause.

Thanks for your efforts.

Thanks for your response.

Normally, IIS would use the process identity (the user account it is running the worker process as) to access protected resources like file system or network.

With passthrough authentication, IIS will attempt to use the actual identity of the user when accessing protected resources.

If the user is not authenticated, IIS will use the application pool identity instead. If pool identity is set to NetworkService or LocalSystem, the actual Windows account used is the computer account.

The IIS warning you see is not an error, it's just a warning.

Please refer to:  Cannot verify access to path

Hope it helps.

This issue just occured for me as well after installing the 2018-09 Cumulative Update for Windows Server 2016 for x64-based Systems (KB4457131) and Security Update For Exchange Server 2016 CU10 (KB4340731) updates.

Note also for me, a lot of files mysteriously disappeared from the "C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa\prem\15.1.1531.4" and "C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\ecp\15.1.1531.6" folders (which I believe are created as part of the Exchange Security Update). I was able to manually copy them over from another server that was patched without issue.
