Question
Explanation
This question tests knowledge of Microsoft Teams coexistence modes and how to apply per-user TeamsUpgradePolicy overrides via PowerShell when an org-wide mode is already set.
Approach. The PowerShell cmdlet used is Grant-CsTeamsUpgradePolicy. For User1, the correct PolicyName is SfBWithTeamsCollab - this mode forces chat and meeting creation through Skype for Business only, while still permitting the user to read and post in Teams channels, exactly matching the requirements. For User2, since the org-wide mode is already 'Teams Only', no per-user policy is strictly needed; however, if an explicit assignment is required, Grant-CsTeamsUpgradePolicy -Identity User2 -PolicyName UpgradeToTeams enforces it. The key insight is that per-user policies override the org-wide coexistence setting, allowing granular control during a phased migration.
Concept tested. Microsoft Teams/Skype for Business coexistence modes (TeamsUpgradePolicy) - specifically the difference between Islands, SfBOnly, SfBWithTeamsCollab, SfBWithTeamsCollabAndMeetings, and TeamsOnly modes, and how Grant-CsTeamsUpgradePolicy applies per-user overrides to the org-wide setting.
