[QUOTE="Marana, post: 1015247, member: 69370"] To answer my own question... At least the following configuration seems to do the trick in a default deny application whitelisting environment: [LIST=1] [*]Whitelist C:\Users\*\AppData\Local\Microsoft\Teams directory structure within SRP all the way down [*]Use NVT OSArmor or similar tool and create a Custom Block rule for the same directory structure [*]Use NVT OSArmor or similar tool and create an Exclusion for the same directory structure for files signed by Microsoft [/LIST] :)(y) However... I still find a little bit odd that I was not able to find any proper discussion of this "problem" either here in MWT forums or elsewhere in the internet. Maybe I just did not find the right keywords to search for... I cannot believe that I'm the only person / we are the only organization who want to use Microsoft Teams securely. :unsure: [/QUOTE]
