Debug Kaspersky Firewall, Outlook calendar sync I need an Outlook-COM-Plugin (communigate pro)

[SuperPotato]

My Kaspersky Firewall of KIS (newest version) is blocking access of my outlook calendar to its server. When I disable the firewall, opening my calendar works.

Since for the calendar sync I need an Outlook-COM-Plugin (communigate pro), I do not know which ports/ files are used in the sync process - it seems poorly documented.

Is there a way to get a detailed log of all blocked connections in order to be able to know where to create an exception rule?

 

Thank you for your help!
