Hi Thomas,

SharedWebConfig.config under C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\ could be missing.

I have checked the web.config file on one of our servers under:
 
C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\EWS and there is a link back to the SharedWebConfig file in HttpProxy:

Within the Assembly Bindings key:

I found this Microsoft description on how to generate the missing file:

https://support.microsoft.com/en-us/help/3099532/event-id-1309-and-you-can-t-access-owa-and-ecp-after-you-install-excha

Hopefully, this helps.

Regards
Sam

Just wondering if any additional steps are necessary either before or after install, or if it’s even safe to install.
