Hello @BRAYYAN KOSTADINOV NIKOLOV,

I understand that you are unable to log in to Teams, both via the desktop application and the web. To better understand the situation, could you please help confirm the following:

Have there been any recent Windows updates? Please check your Windows Update history.
Are there any third-party applications running in the background, such as VPN, firewall, or antivirus software? If so, please try temporarily turning them off, restart your computer, and attempt to sign in to Teams again, as these applications may conflict with Teams.
Could you try switching to a different network (for example, another Wi-Fi connection or a mobile hotspot) to see if the login issue persists?
It may also be helpful to switch to an alternative network to determine whether the issue is related to a network conflict.
- Please navigate to Control Panel > Network and Internet > Internet Options.

Under the Advanced tab, scroll to the bottom and ensure that TLS 1.2 and TLS 1.3 are enabled.

For the web version, please try accessing Teams using an InPrivate window (Edge) or an Incognito window (Chrome).
Please also try signing in to Teams on your mobile device, and check with your colleagues to confirm whether they are experiencing the same issue.

The information above will help me better understand the issue and determine the next steps for troubleshooting. I look forward to your response.

Hello @BRAYYAN KOSTADINOV NIKOLOV,

Based on the current behavior, it appears there may be a compatibility or configuration issue between the Microsoft Teams desktop client and your device.

Since Teams is working normally when accessed through the web and mobile, this indicates that the issue is likely isolated to the desktop application. As a temporary measure, you can continue using the Teams web version without interruption.

For further investigation, I recommend contacting Microsoft Support team. They will support you to collect Teams log and review log files, perform deeper analysis, and check for any known or internal issues that may not yet be publicly documented.

You can submit a support request here: Get support - Microsoft 365 admin | Microsoft Learn.

If you are not a Global Administrator, please help us to reach out to your admin to raise on behalf of you.

For any further concerns or need assistance, please feel free to share with me at any time.

Try the following steps in order, testing Teams after each step:

Confirm Teams version and updates
- In the desktop client, select Settings and more > Settings > About Teams and check the Version.
- Use Update now or Check for updates if available to move off the problematic build.
Fully quit and restart Teams
- On Windows, right‑click the Teams icon in the taskbar and select Quit so it closes completely, then reopen it.
- On Mac, use Option+Command+Esc or Force Quit from the Apple menu, then reopen.
Clear the Teams cache (desktop)
This fixes many issues where the client hangs on loading screens:
- Windows:
  1. Quit Teams from the taskbar icon.
  2. In File Explorer, go to:
    %appdata%\Microsoft\Teams
  3. Delete the contents of this folder.
  4. Restart Teams and sign in again.
- Mac:
  1. Quit Teams.
  2. Delete ~/Library/Application Support/Microsoft/Teams.
  3. Restart Teams and sign in again.
    Note: This removes local cache (icons, thumbnails, local message history, display images, add‑ons) but does not uninstall Teams.
Reset or repair the Teams app (Windows Store / new Teams)
If Teams still freezes:
- Open Settings > Apps > Installed apps.
- Search for Microsoft Teams.
- Select Advanced options.
- First choose Repair. If that does not help, choose Reset (this may delete app data and require signing in again).
Use the web client as a temporary workaround
- Go to the web version at https://teams.microsoft.com/ and sign in.
- If the web client also hangs, this can indicate a broader service or account issue; contact the organization’s IT admin to check Teams service health and policies.
Reinstall Teams and remove leftover data
If crashes or freezes persist even after cache clear and reset:
- Uninstall Teams.
- Manually remove remaining Teams-related folders under the user’s AppData (for example, search for “teams” under the entire AppData tree and delete leftover Teams folders).
- Reinstall the latest Teams client and sign in again.
If Teams for Education or managed tenant
- For school or enterprise environments, some issues (policies, licenses, or tenant‑side problems) must be fixed by the IT admin. If none of the above steps help, escalate to the IT admin to verify access, licenses, and to perform any tenant‑side updates.

If, after all of these, the client remains stuck on loading screens on both desktop and web, collect logs and contact Microsoft Support via the Teams admin center (if available in the organization) for deeper investigation.
