Summary
Details
Updated December 16, 2025: We have updated the content and timeline below. Thank you for your patience.
Introduction
We temporarily paused the rollout of the line key configuration experience in Teams Admin Center (TAC) for Teams phone devices. This pause applied to tenants in Worldwide, GCC, GCCH, and DoD environments. The pause allowed us to address feedback and improve the experience, particularly for shared device license scenarios. As of December 16, 2025, rollout is now expected in January 2026.
When this will happen
We expect to begin rolling out in January 2026. Please see MC1103603 for details.
How this affects your organization
If your organization uses Teams phone devices, you may notice that the line key configuration experience in TAC is currently unavailable. This affects all supported environments. Admins can continue to configure line keys directly on the device as a temporary workaround.
What you can do to prepare
No action is required at this time. We recommend continuing to use on-device configuration until the TAC experience resumes. We’ll provide updated guidance and documentation once the rollout restarts.
Compliance considerations
| Compliance Area | Impact |
|---|---|
| Does the change modify, interrupt, or disable any capabilities (Purview)? | Yes – The pause may temporarily affect audit logging and reporting for line key configurations managed via Teams Admin Center. |
| Does the post describe features/components that have been retired or altered? | Yes – The line key configuration experience in Teams Admin Center is temporarily disabled. |
| Does the post describe any known errors or limitations that were addressed? | Yes – Inconsistencies were identified in shared device license scenarios, prompting the rollout pause. |
