OS: Server 2016 Standard
Software: Exchange 2016
Attempting to upgrade Exchange to CU16. Have dealt with several issues that stopped the install so far, but now getting the following error when it's trying to upgrade the Client Access portion: "An IIS directory entry couldn't be created. The error message is The system cannot find the path specified."
I found things online saying that this indicated a corrupt IIS, so I uninstalled and reinstalled IIS, but that didn't change anything.
I've included the relevant portion of the Exchange Upgrade Error file in case anyone can glean anything from it,
There are extenuating circumstances that make this a significant issue at the moment, and I need to get mail working again quickly, so I hope there is someone out there with some insight right now. This is email for a 911 dispatch center, so it's highly mission critical.
Thank you for any help you can provide.
