Hi @Cookson Myra,
Welcome to the Microsoft Q&A forum.
Thank you for clearly outlining what changed and when it started, your effort helps me narrow down the most effective fix path quickly. Based on your description, you can no longer view contact cards in Microsoft Teams since the January 2026 update.
This behavior commonly occurs when Teams receives an updated Profile/People card experience and the desktop client continues using older cached components. When that local cache or sign-in token state is out of sync, the profile card may not render even though the user account is healthy. In some environments, organization settings can also limit which profile details are shown, which may make the contact card appear empty or not open.
Please follow the steps below that suit for your situation:
1/ Confirm whether this is a desktop-only issue (quick isolation)
- Sign in to Teams on the web: https://teams.microsoft.com
- Open a chat or channel message, then select a colleague’s name to check whether the contact card appears.
- If the contact card works on the web but not in the desktop app, the issue is typically related to the desktop client state and Steps 2–3 are the best next actions.
- Rebuild the Teams local cache (most effective for UI/card display issues)
2/ Windows (New Teams):
- Close Teams completely (right-click the icon in the system tray > Quit).
- On Microsoft: Press Windows + R, then type:
%userprofile%\appdata\local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams - On Mac: Press Command + Q, type:
rm -rf ~/Library/Group Containers/UBF8T346G9.com.microsoft.teams
rm -rf ~/Library/Containers/com.microsoft.teams2
- Delete all contents in that folder.
- Restart your computer and open Teams again.
3/ Reset the New Teams app (deep refresh when cache cleanup is not enough)
- On Windows: Settings > Apps > Installed apps > search Microsoft Teams > select Advanced options > under Reset, choose Reset.
- Launch Teams, sign in again, and test contact cards from both Chat and Channels.
4/ Contact IT administrator
Since your account is managed by your organization, please contact your IT administrator to review your permissions and policies. If the issue persists after these checks, ask your IT administrator to submit a support request directly to Microsoft Support team.
