Hello All,
@Nino Bilic @Vasil Michev,
After we upgrade our exchange from 2019 CU9 to CU11, we start getting below warning every few seconds, tried so many articles also deleted and recreated OAB virtual directories but till the issue same. These three file size is 1 KB global.asax, web.config.bak & web.config ib this location C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\OAB\. it suppose to be 6KB for web.config.bak & web.config.
In one article from Microsoft i read just by replacing the files from working exchange server fixed the issue not sure if its a right solution. appreciate if any one can help us.
