This same folder (also empty) was created yesterday at 5:20pm EST under C:. I was alerted by our file system monitor. I can confidently say this did not appear from anyone doing a deployment, update, etc. on my team. I'm seeing others on the internet report this folder also within the last 5 days. My server is a Windows Server 2016 running Exchange Server 2016. I have other Window Server 2016s but none of them have had the folder appear yet. I have only one instance of Exchange Server 2016 running.
MSIPCCache Folder?

Have no idea what this folder is on my C: root. It's empty. Google search comes up blank which is strange. Thanks

Check with your team if anyone used it as a temporary storage when installing or pushing a change.

It's an empty folder.
