What causes Microsoft Team Error CAA5004b?
Suspicious activities cause the Microsoft Teams error code caa5004b according to its built-in contemporary authentication. Also, VPN usage, account syncing issues inside Windows, multiple active sessions of the Teams app, and piled-up cache files trigger the app to show the error code ca5004b.
Various reasons lead to Microsoft Teams’ error code caa5004b. They are mainly related to your device settings and MS account activity.
I’ve pointed out all the possible reasons behind the error code of MS Teams and listed them below for your better understandings.
So, the reasons behind Microsoft Teams’ error code caa5004b are:
Suspicious Activities
Microsoft Teams has built-in contemporary authentication. So, if there’s any suspicious activity with your Microsoft account, like signing up on an unsafe website with it, then it’ll prompt you to change the password to protect your info from being exposed.
But, sometimes, this sudden password change alerts Microsoft Teams’ failsafe protocol to protect you and your company’s data from leakage and blocks your account from signing in again.

VPN Usage
If you take the help of a VPN to connect with Microsoft Teams, you’re most likely to face the error code caa5004b at startup.
Microsoft Teams relies on real-time connectivity with it’s the remote server. A VPN connection delays this communication and interrupts MS the app’s real-time data exchange with it’s the remote server. That’s why using a VPN causes the MS Teams to show the error code caa5004b and blocks you from signing in to your account.
Confliction Between Windows and Microsoft Teams
If your Microsoft Teams account is not listed inside the Windows account manager of your device, you might face trouble logging in to the MS Teams app because of the error code caa5004b.
MS Teams app syncs your account details from the Windows accounts manager on your pc. If the account is not listed there, MS Teams sometimes recognizes the account as an unauthorized login attempt; that’s why it blocks the log-in process showing the error code caa5004b.

Microsoft Teams’ Policy
If your accounts go against your company’s Team account policy, like frequently changing login locations, you might receive the error code caa5004b. But, if you haven’t changed the login location like the app infers, check if your VPN is active with the auto location setting.
This might create a misunderstanding between the MS Teams policy and your internet connection, causing you the trouble of MS Teams’ error code caa5004b.
Useless Cache Files
In windows, running an app requires generating cache files to operate it’s processes smoothly. Running the Microsoft Teams app repeatedly without shutting down your device piles up a massive amount of cache files. These cache files conflict with each other and interrupt the background processes of the app.
This conflict might be the reason behind the error code caa5004b on MS Teams and causes the difficulties of signing in to the Teams app for error code caa20002.
