Summary:

Updated February 28, 2025: We have updated the rollout timeline below. Thank you for your patience.
Coming soon: We will introduce a new Microsoft Teams PowerShell setting in Tenant Federation Configuration to enable you to customize your federation posture.

[When this will happen:]
General Availability (Worldwide): The new setting is available now in Teams PowerShell. If populated, the allowed trial tenant domains list will start to take effect in mid-March 2025 (previously mid-February).
Note: This feature requires no immediate admin action, and there will be no impact if the list is not populated.
