Our company uses Office 365. A user left and our IT team confirms that her account was disabled in June. There's a document in SharePoint showing that she created it in April (ok) and edited it in July (not ok). As I have the approval/rejection workflow turned on and her edits were never approved, the document remains in a status of "Pending." I ran all the audit reports SharePoint offers but could find no record of her editing this document.
Is there any way to figure out what actually happened?
