Office 16 (Word, Outlook, Excel) QAT blinking on several users

Hey Experts.  Odd issue being reported on four of my Windows 7 computers.  I deployed 20+ updates to several OU's on Saturday night.  On Monday, 4 computers out of 20 in one OU reported that when they open Word, Outlook or Excel, the QAT blinks repeatedly and makes the app unusable.  No other computers in any of the other OU's reported any problems.  3 of the computers are the same model (hp dc5750) and 1 is an HP 3130.

I compared the 4 experiencing an issue to a couple out of the 20 working computers to see if there was any glaring differences and even after checking for differences in Office/OS patches, or computer driver versions, nothing sticks out.  

So far I've:
  • run a repair on the Office suite
  • tried starting the various apps in safe mode
  • logging in with a different user account (including one with admin rights)
  • deploying additional Office 2016 patches to one of the computers so it was completely up to date

I'm out of ideas.  Any suggestions on where to go next or how to trouble-shoot further?  Thanks in advance experts!

This issue has been reportedly caused by Skype for Business (Microsoft Lync) in Office builds. If you don't use Skype for Business, navigate to Microsoft Office in Programs and Features, highlight the entry and then click change. You should be able to go in here and disable Skype For Business/Microsoft Lync. Reboot the PC and then run Office once again and see if this corrects the issue.

Thanks for the quick reply and information.  I don't see Skype or Lync installed.  I do see that I let updates slip past and get installed for those apps.  I normally filter them but this time they got installed.  I'm uninstalling them now and going to see what that does.

Uninstalled the skype/lync updates.  After that, restarted the computers.  The issue remained.

I had user A log into one of the other computers that were experiencing the issue.  When user A logged in and opened Outlook/Word, the issue wasn't present.  Narrowed the issue down to being associated with the profile.  Going to delete the user profile that's experiencing the issue on the 4 pc's and update accordingly.
10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

To your comment about not seeing either installed, did you follow the steps I listed in my post on disabling the feature in office? If not, it will just show as part of the Office installation. I came across a situation prior with my boss not wanting Skype for Business on his machine. It was showed as not installed but going into Office to change it's features showed that Lync was enabled. Disabling Lync also removed Skype for Business. It comes as a feature now instead of standalone software.

Here is a snapshot of the way Office 2016 is configured.  Let me know if Skype for Business is removed.  Thanks William.

As a follow-up, I deleted User A's profile from the registry, had User A log back in and test Word.  When User A opened Word again, the QAT continued the rapid blinking.  Not sure where the Office 2016 settings are housed.

So it's definitely not installed according to the Office features listed in the screenshot. Another person has noted that disabling certain services related to Intel on-board graphics has fixed the issue for them. I've also seen strange things like this (though not specifically in a program) happen when you have a corrupted installation of the AMD Catalyst software.

I checked the drivers and after seeing there wasn't much progress, I gave the issue to the helpdesk to have the pc's re-imaged.  I appreciate your help.  Working on the wrap-up for this question now.
