Error 1200: Something went wrong when signing

Anonymous

When I tried to send an Teams invite on Outlook, I received a pop-up message of "To schedule a Teams meeting, make sure you're signed into Teams", which I was actually signed in. To refresh it, I then signed out of Teams, closed the app and tried to signed back in but it was unsuccessful.

It showed an error of "Something went wrong. [1200]" I have also cleared the cache as some suggestions but it didn't work. I can sign in Teams on web and used other Microsoft apps no problems.

Please can someone help me!!

    Dear Darcy_Lindner,

    Good day!

    Thank you for posting to Microsoft Community. We are glad to assist!

    Based on your description regarding "Error 1200: Something went wrong when signing". May I please know if you are using windows or Mac device? If you are using Windows device, kindly check with below methods to see if it will make any difference:

    Note: Before performing this, kindly close all office Apps.

    ++ Kindly try to disconnect account from Work access or School:

    1. Click On Windows Start Menu
    2. Settings
    3. Accounts
    4. Work Access or School
    5. Select the account and click on Disconnect

    ++ Kindly try to clear credentials

    1. Open Control Panel > Credential Manager.
    2. Select Windows Credentials
    3. Remove all Windows credentials listed for Office16 by selecting the drop-down arrow and Remove. (remove credentials related to the account you want to sign into)

    ++ kindly try to remove the account from Registry key

    1. On your keyboard press Windows Key +R(Or Click on Windows Start Menu and Search Run)
    2. Type Regedit
    3. Navigate to this path : HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity
    4. Expand Identities folder
    5. Select on each folder and check which folder shows the email address of the account you want to sign into
    6. After locating the folder, please right click on it and delete

    If the issue persists, would you mind offering below information:

    • May I know your current environment? Is It Exchange Hybrid, on-premises exchange (Exchange server) or pure cloud?
    • Could you please provide entire screenshot of the error and pop-up message you're experiencing or your current situation? (Please hide information such as email for the privacy of your data)

    Looking forward to your response.
