I currently am working remotely and we use teams to communicate within our office.  Teams has given intermittent troubles.  It will not allow me to login sometimes.  When this happens I have to uninstall and reinstall the application, now that won't work at all.  I like to run the teams app on my local computer while using work vpn.  Currently using the web app to work.  Even an uninstall and reinstall will not work.  Please help. 

Error code - caa70004

There's a more permanent way to sign in to Microsoft Teams. If you're having trouble completing the process, talk to your IT admin

    Hi Filmonl，

    Given this situation, we’d give you some suggestions below and hope that will help you:

    1. Type Credential Manager in Windows search box and open it.
    2. Open Windows Credentials tab remove all the credentials named msteams_adalsso/adal_context

        Note: Please back up first before you delete them.

    1. Sign out Teams desktop client and exit Teams completely. Go to %appdata%\Microsoft\teams\Cache and delete all the files. Then go to %appdata%\Microsoft\teams\Application Cache\Cache, delete all the files. Re-open Teams to see if you can sign in successfully.

    Meanwhile, I'd like to confirm the application's version number as well. What account do you use to log into the Teams application?

    Best Regards,

    Cliff

    Hi Filmonl,

    Sorry for the trouble caused by this issue.

    Based on our search, seems like this issue is related to modern authentication of Microsoft Teams.

    Microsoft Teams has implemented a better way of signing in, the benefit of modern authentication is that it makes it possible for you to sign in to Microsoft Teams without re-entering your email and password every time you want to start a new session. As you already tried the steps but no luck, there might be something wrong with your domain or your company's Office 365 account.

    We sincerely suggest you contact your IT admin with the error code to fix this issue. Here is the article for your reference: Why am I having trouble signing in to Microsoft Teams?

    You are welcome to contact us if you need further help.

    Best Regards,

    Ivy

    Is there a way to make it take me authenticate.  If I could type in my password it would work.  But it never prompts me.

    Hi Filmonl,

    We suggest you try to do the same steps to try to sign in.

    1. Click the Maximize "Square" button to make this full screen when you see this screen:

    1. After making this window Full screen click on "Singing out" again and this time it will actually work.
    2. Enter your account and password in dialogue box to check the result.

    You can feel free to share the outcome with us. Thanks for your cooperation.

    Regards,

    Ivy
