For Using VPN
If you connect to Microsoft Teams over a virtual private network (VPN), you will almost certainly see the error code caa20002 during the starting process for Microsoft Teams.
MS Teams need a connection on a real-time basis with the remote server in order to function properly. The use of a virtual private network (VPN) may cause a delay in this connectivity and will disrupt the real-time data transmission that MS Teams does with its distant server.
Because of this, utilizing a virtual private network (VPN) will result in the Microsoft Teams application giving you an error message with the code caa20002 and will prevent you from logging in to your account.
Windows Account and MS Teams Are Different
You can have issues signing in to the Microsoft Teams app due to the error number caa20002 if the account you use for Microsoft Teams is not registered inside the accounts area of Windows on your device.
The account information is synchronized from the Windows accounts manager on your own computer to the MS Teams app. MS Teams may occasionally detect an account as an illegal login attempt if the account is not mentioned there.
Because of this, MS Teams will prevent the account from logging in and will display the error number caa20002.
Logged In in Several Devices
If you are currently signed in to Microsoft Teams on numerous devices and attempt to enter in again after having already logged out, the Microsoft Teams app may detect this as an illegal login attempt and provide you with the error number caa20002.
You will continue to receive the error code caa20002 regardless of how many times you attempt to log in.
Since this is the case, login into MS Teams from more than one device will result in the Microsoft Teams app displaying the error number caa20002.
MS Teams Policy Violation
It’s possible that you’ll get the error number caa20002 if the policy for your Team prevents users from regularly changing where they log in. Whether you are working from home but have not switched the login location, check to see if your VPN is functioning with the auto location option enabled.
Because of this, there is a possibility that a mismatch may arise between the policy of Microsoft Teams and your internet connection, which will result in the occurrence of error code caa20002 for Microsoft Teams.
Conflicting Cache Files
When using Windows, it is necessary to generate cache files for an application before it can be started so that its processes can function smoothly. When you use the Microsoft Teams app on your smartphone frequently without giving it a chance to shut down, a significant number of cached data will be created. These cache files are incompatible with one another, which causes a conflict that disrupts the app’s background activities.
It is possible that this disagreement is the origin of the problem code caa20002 on MS Teams, which in turn creates issues in signing in to the Teams app with the error number ca20002.
