It is a known problem when you have Cisco AnyConnect installed, and it is supposed be be solved when Big Sur 11.2 gets released. @Tulli Here’s the response from Kaspersky Tech Support: The issue is known and is related to a Big Sur bug: From the logs we can see that the Cisco client is installed. Apple have stated that they will fix this issue in the release of macOS 11.2. Unfortunately, this means you will need to wait for that release before the issue can be fixed. Merry Christmas :-)

Kaspersky Support have escalated it now.

Got a reply now asking for more information. Provided.

Thanks Alex, I submitted a screenshot and both agent and app trace logs. It’s INC000012200313 - I’ll let you know when I get a useful response.

Hi Tulli, Funny thing, I installed the Cisco Webex Productivity Tools now, and I get the same too. “A glitch in connecting to the Webex service” when I open Outlook.

Thanks Alex, appreciate the suggestion! Unfortunately it didn’t work for me. Same problem. I never tried installing 11.0.1 on Big Sur. I did install 11.1 on Catalina before upgrading and that was working fine - also with Outlook 365. I’ll open a support ticket and let you know what they come up with. Thanks again for taking the time to respond - much appreciated!

Is there a known issue with Exchange connectivity using KESB 11.1.0.210 on Mac OS Big Sur? I installed a brand new test machine with Mac OS Big Sur 11.0.1, and it went fine. Installed Office 365 and configured Outlook to connect to our on-premise Exchange 2019 server. All was good. Then I installed Kaspersky Endpoint Security for Mac 11.1.0.210. And now Outlook is unable to connect. Everything else that I tested works fine. No matter whether I enable or disable HTTPS encryption inspection it fails to connect. If I disable protection in Kaspersky, it still fails. If I Quit Kaspersky, ít connects just fine. I’ve tried re-installing Kaspersky. I even tried re-installing Mac OS Big Sur. But it is still the same. Nothing is blocked in Reports, so I am sort of clueless as to why it’s blocking. Anyone else experienced this? Or anyone who has any ideas?
