We are receiving an unusual high amount of failing "Kasperksy for Workstation 22.214.171.12499" Outlook add-in's and corrupt OST files since we have migrated our machines from Windows 7 to Windows 10 and Office Version from 2010 to 2016.
We have an on premise Exchange 2013 server and the Kasperksy for Workstation version has remained unchanged. So only the Office version and the OS has changed on the workstations.
So far I have not been able to find the culprit. I was wondering if more people experience a failing Kasperksy add-in or if they see higher than usual corruption of the OST files.
As the Kasperksy add-in is the only add-in we have in Outlook, my first thought was that perhaps Kasperksy could be a culprit to this. We had negative experiences with this add-in in the past causing very slow Outlook performance.
Outlook disabled the following add-in(s):
