Why each option
To properly plan for firewall and proxy requirements for Microsoft Teams, it is essential to whitelist the specific URLs and IP addresses that Teams uses to communicate with Microsoft 365 services.
While opening specific ports (TCP 80, 443, and UDP 3478-3481) is part of the requirements, it's often insufficient on its own for proxies and firewalls without also allowing the specific FQDNs and IP ranges.
Microsoft Teams relies on specific FQDNs and IP address ranges for its services, which must be whitelisted in firewalls and proxy servers to ensure proper connectivity and functionality. This is a primary step in configuring network security for Teams.
"Assess the network requirements" is a prerequisite step, but it doesn't describe the how to implement the firewall and proxy configurations for Teams.
"Implement a proxy server" is a general network infrastructure decision; the question asks how to plan for its requirements specifically for Teams.
