Defender CFA "blocked" Excel notification but nothing blocked. RRS feed

  • Question

  • Why would I get a "Protected folder access blocked" notification from Defender when I open an xls under the conditions listed below?

    The app is EXCEL.EXE, the folder is D:\Documents\Receipts.

    1. I've accessed the same xls in that same folder many many times in the past and gotten no "blocked" notification so apparently it has not been necessary to add EXCEL.EXE to the Controlled Folder Access  "allowed app" list in the past.

    2. D:\Documents has always been on the CFA protected folders list.

    3. Even though the message said access was blocked, the xls opened fine.

    I have made no changes since this happened. I did not add Excel.exe to the allowed list, but I can now open the xls without any Defender notifications coming up.

    Sure I can ignore the incident, but any ideas about what happened?
