Hello Raja Laxmi,
Thank you for reaching out. The error code CAAC000E usually occurs when there is an issue with the authentication process. To resolve this issue, please try the following steps:
- Clear the cache and cookies of your web browser.
- Check if the date and time settings on your virtual machine are correct.
- Make sure that your virtual machine is connected to the internet.
- Try signing out and signing back in to Teams and Office applications.
- If the issue persists, try resetting the Microsoft Store cache by running the following command in PowerShell as an administrator: "wsreset.exe".
If none of the above steps work, please provide us with more information about your virtual machine and the version of Teams and Office applications you are using. We will be happy to assist you further.
