July 24, 2020 by Madalina Dinita 13 Comments

Remote work has become very popular lately due to the unexpected global health issues that took the whole world by surprise. As a result, many companies and professionals are now relying on collaboration software to carry out their daily business operations and work remotely.

Microsoft Teams is one of the most popular remote work and collaboration software in the world with tens of millions of users. Taking into account this huge number of users, it’s understandable that the tool may stop working from time to time.

In this guide, we’re going to focus on a specific Microsoft Teams error that’s been bugging a lot of users lately, namely error code caa30194. This error usually occurs when users try to log into the platform using the desktop client but the desktop app is failing to connect.

Fix Microsoft Teams Error caa30194 With These Solutions

1. Clear the Teams cache

This basically means you’re going to delete all the Microsoft Teams temporary files stored on your machine. Here are the steps to follow:

  1. Close your Microsoft Teams desktop client
  2. Open File Explorer
  3. Type %appdata%\Microsoft\teams to open the Teams directory and access the folders stored there
  4. Go to Cache and delete all the files from the Cache foldermicrosoft teams cache folder
    • To quickly access the Application Cache, you can also type %appdata%\Microsoft\teams\application cache\cache in File Explorer
  5. Go to the Blob_storage folder and delete all the files you find in that folder
    • Again, you can access the Blob_storage folder directly by typing %appdata%\Microsoft\teams\blob_storage in File Explorer.
  6. Go to the Databases folder (%appdata%\Microsoft\teams\databases) and do the same
  7. Open the GPUCache folder (%appdata%\Microsoft\teams\GPUcache) and delete all the files
  8. Now, go to the IndexedDB folder (%appdata%\Microsoft\teams\IndexedDB) and delete only the .db file
  9. Next, navigate to Local Storage (%appdata%\Microsoft\teams\Local Storage) and delete all the files stored in the respective folder
  10. And the last step is to go to the tmp folder (%appdata%\Microsoft\teams\tmp) and delete all the files.

You can now restart Microsoft Teams and check if the error is gone.

2. Delete JSON files

Sometimes, your JSON files in the Teams installation location (%appdata%\Microsoft\teams) might get corrupted and this could potentially prevent users from logging in.

To fix this problem, delete all 4 JSON files along with logs file from %appdata%\Microsoft\teams.

    none of this worked. After reinstalling 5 or 6 times it finally worked again and the next day it again says I’m offline. I just gave up and used it in browser, what a trash software.

    I can’t get access on my laptop, It works on my phone and other famiy members’ devices, though. I try to follow the guidance but it won’t work! Even if I successfully get access, I’m always get kick out of the meeting, even though my wifi works fine and other devices can access normally…

    I did all of these, and none worked.
    Also, the “solution” of using the web version isn’t a real solution at all. It doesn’t fix the problem, it just makes it so you will have to deal with it later. The problem is still there.

    I have tried every single one of these things and none of them work (including setting compatibility to Windows 8). I can run MSTeams in the web browser but I cannot get into the app at all.

    Thanks for the one who came up with the solution to run it as Windows 8 compatible. Nothing in this thread but this actually worked for me.

    I have tried everything and it still does not work for me. Unless i manage to open a meeting link and join as a guest, it does not let me log in to my account.

    Thank you, YourLocalItGuy. Running Microsoft Teams in Compatibility Mode for Windows 8 solved the issue for me.

    If none of the above worked for you, find the App icon, right click and open properties, then go to compatibility and run in compatibility mode for windows 8.
