Have no idea what this folder is on my C: root. It's empty. Google search comes up blank which is strange. Thanks
What types of files are in this folder?
It's an empty folder.

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.
My setup is Windows Server 2012 R2 running Exchange Server 2016. Possible security breach?
MS usually would be Microsoft. IPC is Interprocess communication (IPC) It's worded very microsoftish
None. It's empty.
From the looks of it and lack of anything in any search engine, it most likely has to do with a temp folder created from a deployment in your environment.
Check with your team if anyone used it as a temporary storage when installing or pushing a change.

So Heather and I are the only people in the world that have noticed this mysterious folder appearing? It's weird that nobody seems to know anything about it.
It makes me feel sorta special. :-) LOL!
We ended up double checking event logs and even firewall traffic to the public IP of our Exchange server. Absolutely nothing out of the norm has been found yet. We have not had this folder created on any other server in our environment either.
