Carbon Black App Control (formerly Cb Protection)

Issue/Introduction

Endpoints running the App Control Agent version 8.5.0 or lower experience slowness/freezing issues when opening MS Office 365 applications (Most obvious examples are Excel.exe and Outlook.exe).

Environment

  • App Control Agent: 8.5.0 and Lower
  • Windows OS: All Supported Versions
  • Microsoft Office 365

Cause

The App Control Agent isĀ continuously seeing ABMiss Ops on MS Office 365 applications. The DeletePending flag gets set on one of the links, but is never cleared. Thus, every time the application is closed the agent treats it as a delete operation.

Resolution

This is an issue that is going to be resolved in theĀ 8.6.2 (or Higher) App Control Agent release, which is still not yet officially scheduled for a release date, but is expected Q2 of 2021. This article will be updated when that date has been made official. For those affected that need additional and immediate assistance, please open a Support case for additional options.
