Description: Several active group chats are failing to appear in the "Chat" list on the macOS desktop application. These chats remain fully functional and visible on both the iOS mobile app and the Web version (https://teams.cloud.microsoft.mcas.ms/). The issue appears specific to the macOS local environment and persists across app restarts.

Environment details:

  • App Version: 26032.605.4378.6183
  • OS: macOS 13.7.8 (22H730)
  • Device: MacBook Pro 2017

Steps to Reproduce:

Open Microsoft Teams on macOS.

Navigate to the "Chat" tab.

Search for or scroll to specific group chats known to be active.

Observe that the chats do not appear in the list.

Open Teams on iOS or a Web Browser and observe that the same chats are visible and updating.

Expected Result: All chat threads should synchronize across all platforms and be visible on the macOS desktop client.

Actual Result: Specific group chats are hidden or fail to sync on the macOS app, despite being active on other platforms.

Troubleshooting already attempted:

  • Logged out and logged back into the account.
  • Fully uninstalled and reinstalled the Teams macOS application.

    Hello Misha Andreev,

    Thank you for posting your question in the Microsoft Q&A forum.

    Based on your description, the issue might relate to local cache corruption, profile data issue, or client-side sync defects in Teams for MacOS.

    For my recommendation, kindly follow these steps to completely clear Teams cache: Clear the Teams client cache - Microsoft Teams | Microsoft Learn and try to login once over again to check if it can resolve the issue. In the meantime, also check on the Teams web to check if this behavior affects both environments.

    In case the issue still persists after cache clearing, my recommendation is to have your IT admin open a support ticket (or you can manually do it if you are a Global Admin of your tenant) via Microsoft Admin Center by following this article: Get support - Microsoft 365 admin | Microsoft Learn so that the support agent can investigate further.

    Note: Please understand that as a forum moderator, my primary goal is to provide helpful guidance and support through general troubleshooting steps. While I don’t have access to internal systems or test devices required to resolve backend/account issues, I truly appreciate your understanding of these limitations.
