About this tag
The external collaboration tag covers Microsoft Teams administration, security, and planning for interactions with users outside an organization. Current topics include Teams Premium GCC licensing decisions ahead of Advanced Collaboration Analytics, which is scheduled to begin rolling out in October 2026 and requires time before data becomes available.
