💡 Our Technical Review in summary
Summary
- Update Overview: Microsoft is redesigning the “Activity in other accounts and orgs” panel in Teams (Windows and Mac desktop) to streamline cross-tenant collaboration and reduce the need for constant tenant switching.
- Key Timeline: Targeted Release begins mid-November 2025. General Availability for Worldwide, GCC, and GCC High is scheduled to begin mid-March 2026 and complete by late March 2026. DoD rollout follows in late March 2026.
- Core Objective: To allow users to triage and respond to notifications from different organizations and accounts without losing their current working context.
Impact
- UI Shift: The entry point for cross-tenant activity is moving from the top-right corner to the bottom-left sidebar. The icon only appears for users with multiple accounts or tenants.
- Centralized Notifications: The new panel displays a cumulative count of missed activities across all accounts/tenants. Selecting an activity will open it in a child window, allowing the main Teams window to remain in the current tenant.
- Tenant Pinning: Users can pin up to three specific tenants to the sidebar. Pinned tenants will show their own activity badges and remain visible even when there are no new notifications.
- User Efficiency: This update significantly reduces “context switching” fatigue by eliminating the manual process of switching orgs just to check notification details.
- Current Limitation: A known issue exists where cross-cloud notifications (e.g., between Commercial and GCC) do not yet appear in this panel, though Microsoft expects to resolve this by late November 2025.
Action Required
- User Education: Update internal training materials and help desk documentation to reflect the new location (bottom-left) of the multi-tenant activity icon.
- Feature Awareness: Inform “power users” who manage multiple organizations about the ability to pin up to three tenants for faster access.
- No Configuration Needed: This feature is enabled by default. Admins do not need to perform any technical configuration, as the panel respects existing tenant and account policies.
- Monitoring: Watch for the updated documentation promised by Microsoft prior to the General Availability rollout to share with your technical support teams.

Severity: normal
Updated January 30, 2026: We have updated the timeline. Thank you for your patience.
[Introduction]
We’re improving the panel which shows your Activity in other accounts and orgs in Microsoft Teams to streamline how users triage and respond to cross‑tenant activity. This update reduces the need to switch tenants, helping users stay in context and collaborate more efficiently across organizations.
This message applies to Teams for Windows desktop and Teams for Mac desktop.
[When this will happen:]
- Targeted Release: Begins rolling out November 16, 2025; expected to complete by November 20, 2025.
- General Availability (Worldwide): Begins rolling out mid-March 2026 (previously late January); expected to complete by late March 2026 (previously late February).
- General Availability (GCC, GCC High): Begins rolling out mid-March 2026 (previously early February); expected to complete by late March 2026 (previously late February).
- General Availability (DoD): Begins rolling out late March 2026 (previously mid-February); expected to complete by mid-April 2026 (previously mid-March).
[How this affects your organization:]
- Who is affected: All Microsoft Teams users with multi‑tenant, multi‑account configurations.
- What will happen:
- Users gain an improved centralized panel for viewing cross‑organization and cross-account activity notifications, eliminating the need to manually switch organizations or accounts to check notification and activity details. This improves responsiveness and reduces context switching.
- The entry point for the panel that shows Activity in other accounts and orgs will move from the top-right corner to the bottom-left sidebar in Teams. The entry point icon will appear only when you have more than one account or tenant available to you.
- The entry point icon will display a count of total missed cross‑org and cross‑account activity notifications.
- Selecting the icon will open a panel which will show missed activity notifications across all orgs and accounts, grouped by each tenant. If there is no missed activity in a tenant, it will not appear in the panel.
- Selecting an activity inside the panel opens it in a child window, preserving the context in the main window.
- Users can pin up to 3 tenants to the sidebar to stay updated. Pinned tenants remain in the sidebar even if there is no missed activity.
- Selecting a pinned tenant shows a panel with missed activity notifications from that tenant only. Notifications from pinned tenants do not appear in the main panel for activity in other accounts and orgs.
- The feature is enabled by default for tenants where multi‑tenant or multi-accounts are supported and available.
- No admin configuration is required, the updated panel respects existing tenant and account policies.
Before rollout, we will update this post with new documentation.
[What you can do to prepare:]
- Communicate this change to users, including the new location of the Activity in other accounts and orgs panel and the ability to pin tenants to the sidebar.
- Monitor adoption and gather feedback for future iterations.
- No admin action is required for rollout.
Known issue: Cross-cloud notifications do not appear in the Activity in other accounts and orgs panel at this time. This capability is actively being worked on and is expected to be available by the end of November 2025.
[Compliance considerations:]
No compliance considerations identified, review as appropriate for your organization.
