Imagine the Microsoft Teams app kicks you out during a session and tells you to sign in again. After signing in, it asks to reset your password, and now it’s not letting you sign in, showing the error code caa5004b after a password reset. Sounds familiar?
Since the pandemic forced us to stay at home, I often faced the error code caa5004b while using Microsoft Teams for my home office.
After wasting hours of my time and energy, finally, I found the reasons behind this error and successfully fixed them.
So, What is Microsoft Team’s error code caa5004b?
Microsoft Teams error caa5004b means the MS Teams is facing trouble with built-in contemporary authentication. This error occurs due to suspicious activities with MS account, your domain issues, VPN usage, redundant cache files, syncing complications of MS Teams’ or MS 360 account with Windows.
Read the whole post without skipping any part to identify and fix the Microsoft Team’s error code caa5004b.
Also, check out our separate post on how to Use a Green Screen with Microsoft Teams.
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.
Follow our guide to How to Export Chat History in Microsoft Teams
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.

Multiple Device Login
If you’ve multiple sessions of the Microsoft Teams app running on various devices, the app might recognize it as suspicious account activity and show you the error code caa5004b.
No matter how many times you try to log in, you’ll get the error code caa5004b.
That’s why logging to MS Teams from more than one device will end in receiving the error code caa5004b on Microsoft Teams app.
Follow our guide to How to Record Microsoft Teams Meeting
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.
So, I won’t be wasting your time anymore with technical jibber-jabber and directing you right away to the solution of Microsoft Teams error code CAA5004B.
But, I suggest you not rush while applying the solutions I’ve listed below to solve the MS Teams error code caa5004b.
Read the solutions carefully to avoid any errors before applying them.
So, the methods for solving the Microsoft Teams error code caa5004b are:
1. Turn Off VPN

Given this circumstance, you should contact the administrators of these groups and request that they remove you from their organizations and re-invite you to see what happens.

We’ve also created a video that walks you through the steps given above. Follow along with our YouTube video here:
This will edit the settings and start the process with your confirmed signature. Even if it’s the current account you’ve confirmed on teams, the content folder may fail to register any subsequent login attempts since it retains your credentials from prior logins.
The error is caused by sign-in issues. As with most Teams’ errors, a lack of secure sign-in causes these errors and makes it difficult for Teams to allow you to access the program. You can resolve this issue by resetting the panel using the method above, however, to ensure the error does not get restored, we highly advise users that they use Modern Authentication to verify sign-in.
What is Modern Authentication
Modern authentication is a new technique of signing that Microsoft Teams has adopted. (If you’ve ever heard the term “single sign-on” or “SSO,” you’re on the right track.) Modern authentication has the advantage of allowing you to sign in to Microsoft Teams without having to re-enter your email and password every time you want to start a new session. It’s a more secure and dependable method of accessing Microsoft Teams.
Modern authentication is a technique for securely logging into an app. Because contemporary authentication incorporates SSO, it’s also a component of the process that informs Microsoft Teams that you’ve previously provided your credentials (such as your work email and password) elsewhere and shouldn’t have to do so again to start the app.
Signing in using contemporary authentication will differ based on a few factors, such as whether you’re using Windows or a Mac. It will also differ based on whether your organization uses single-factor or multi-factor authentication (multi-factor authentication usually involves verifying your credentials via your phone, by providing a unique code or entering a PIN number, or presenting your thumbprint). In any case, after you finish the modern authentication sign-in procedure, you won’t have to enter your credentials again—Microsoft Teams will automatically sign in to your account whenever you start the app from the same workstation.
Why can’t users sign into Teams
Modern authentication is fantastic, but it’s possible that a company will run into difficulty now and again.
Every enterprise that utilizes Microsoft Teams already has contemporary authentication built in—the app was built with it, and it should be able to identify your credentials as being tied to your Office 365 account. If you’re having trouble signing in, it’s possible that something is wrong with your domain or your company’s Office 365 account. Your IT administrator or sysadmin will be your point of contact for addressing the problem, so contact them for further information and next actions.
As well as the domain you may find that the login credentials could also be faltered and may not be recognized by teams. You can check this by resetting the password and trying to see if this resolves the issue and if not, your device needs some form of verification to prove it’s part of the organization. You can ask your administrative staff members to verify your IP address and grant your device access to a network or if you use a personal account, you can also achieve this by accessing your personal SharePoint account and managing your IP from there.
In depth – Step by step process – How to fix Teams error code caa5004b
Step by step breakdown:
- Type settings in the Windows Search box and press Enter.
You can also locate the settings panel in the Windows app drawer.
- Select Accounts from the drop-down menu.
As mentioned before you can manage accounts here and a selection for this is available, just click on it.
- Select Work or School from the drop-down menu.
Your school or work account are the ones to get the error as they are mandated by a network you are a member of.
- Disconnect your company’s email account.
- To reconnect your work account, click Connect and enter your Organization email address.
- Restart the Team’s Client.

Microsoft Teams is a great resource if you have meetings with colleagues and works as an alternative to Zoom. However, Microsoft teams doesn’t come without errors. With error codes such as caa5004b appearing regularly. Although there are a few known errors for the Microsoft team, we will be looking into the error code caa5004b. If you’re unsure what this means and how to fix it, you’ve come to the right place.
What does error code caa5004b mean?
This error code is used when you are experiencing sign-in issues. A common issue that can occur when you are trying to sign in is accessing the organisation. Sometimes this happens if the domain is wrong or you can’t sign in. However, this also can happen if you do not have access to a particular organisation, e.g. your account has not been set up correctly. We firstly recommend trying to contact the administrator for the group. They can check access has been set up correctly for you.
If this has been set up correctly or if you were able to gain access previously, ask the admin to remove you from the team, then reinvite you and see if this fixes the error. But if you are still getting the same error, here is a step by step guide on how to fix this error code.
Method 1 to fix caa5004b
- Into the search bar of Windows, type settings
- Go to accounts > access work or school
- Disconnect your organisation email, e.g. work email
- Click yes on the pop-up, then allow 2-3 minutes for the account to be disconnected
- Next click connect (like the first time you logged in), then type in your email address
- Once you’ve done this, you should be able to restart teams, and it should work
However, if method one did not solve your issue, please take a look at method 2.
Method 2 to fix Microsoft teams error code caa5004b
If the above method did not work for you, here is an alternative method that is a little bit more tricky, but it works. In this method, we will clear the cache for Teams.
- Close down Teams and make sure it is fully closed
- Search for File Explorer in the search bar > open
- Type in %appdata%Microsoftteams.
- Once you are in the directory, you will see a range of different folders. Start with ‘Application Cache’, go to Cache and delete any of the files in the Cache location
- The other folders you should be looking for and deleting any files are:
“%appdata%Microsoftteamsapplication cachecache”.
“%appdata%Microsoftteamsblob_storage”.
“%appdata%MicrosoftteamsCache”.
“%appdata%Microsoftteamsdatabases”.
“%appdata%MicrosoftteamsGPUcache”.
“%appdata%MicrosoftteamsIndexedDB”.
“%appdata%MicrosoftteamsLocal Storage”.
“%appdata%Microsoftteamstmp
- Restart the team
- Next, you will need to clear Windows credentials. You do this by controlling pannel > credential manager > windows credentials > generic credentials and removing any items related to Microsoft Office and Microsoft Teams.
- Sign in, and your teams should now work again.
If you’re still unable to fix this error by either of these methods, it may be a more complex issue that requires specialist technical help. To get this, please reach out to the Microsoft Team for help.

In my upgrade testing I have been experiencing some issues with machines connected to Azure AD and its been quite a ride to figure out how to correct it!
I have mapped out what exactly has happened and now the sun is now rising again as I have a tested and working solution!
I just need to get Microsoft to confirm that the upgrade is causing the issue and help work out the issue as to why this is happening.
Here is my synopsis of the issue, I know I am not the only one that has seen this issue, on the MS Answers Forums you can reference here and here. This is what is actually what is happening — Prior to the issue, the machine is connected to AzureAD and logged on and authenticated with an AzureAD account. A new upgrade in Settings —> Update & Security will download a new #WindowsInsider build.
In all cases that I have seen this issue, the machine had been previously renamed after it was joined to AzureAD, but I can neither confirm nor deny if this is part of the issue.
After the upgrade an attempt to login with the AzureAD user account gives a bad password prompt, even though the password is correct. After some investigation I figured out the real problem, the #WindowsInsider Build upgrade has disconnected it from Azure AD! How to confirm this? I had setup an LocalAdmin account on my test devices knowing that I may need a way to get into the computer in the event that my azure AD account was unavailable.
Logging in as the LocalAdmin I verified a couple of settings, first things I did was login to the FeedBack Hub and attempt to sign in as my Azure AD account
Here is the CAA5004B error that I have been seeing, the error comes back as Device Information is missing — I went back and checked inside the settings application to validate that I was connected to my Azure AD
in the Settings —> Accounts —> Access Work or School was enabled. Something looked a little strange, it shows that I am connected to an Azure AD but it doesn’t look like it normally does, I try a disconnect and I am not allowed. My original solution was to completely reset the computer — This does work, is extremely drastic, and isn’t the best solution.
Here is the fix!
I figured out the right way to address the issue without reseting the computer!
Even though the settings application sees that I am connected to Azure AD I had a sneaking suspicion that I really was not connected at all — I just needed a way to confirm this, thankfully Microsoft has a command that lets us know in detail what exactly is the status of our domain join
DSREGCMD /status
This command
Tells the real picture — After the upgrade my machine has been unjoined from Azure AD! This is a huge problem! I checked my Azure AD and the last machine update (Get-AzureADDevice) showed that my machine was updating and was on build 18323 — This upgrade was to 18329.1 — something removed the domain join on the machine and didnt touch Azure AD. Ok now I know why the user couldn’t login, no domain to authenticate, no way to login!
Now how to get it to Rejoin Azure AD!
For me, I could not disconnect and reconnect it to Azure AD in Settings —> Accounts —> Access Work or School as It would not let me Disconnect as it was already disconnected — To disconnect the domain I needed to run DSREGCMD as system!
PSEXEC -i -s cmd
A handy Windows Sysinternals utility to the rescue! PSEXEC (A tool every ITPro uses!) lets you run a command prompt in the NTAuthoritySystem context interactively! After I spawned a cmd prompt running the Command
DSREGCMD /Debug
Verified that I was not connected and that the only way I could get out was via the
DSREGCMD /Leave
This command run in the NTAuthoritySystem context removed the hidden Azure AD connection.
In Settings —> Accounts —> Access Work or School I went through the process to rejoin Azure AD (Hit the Connect and then ensure you choose Join Computer to Azure AD with your Azure AD account)
Now this looks Better! It now shows that the machine is connected to my corporate Azure AD — To confirm that the machine was actually connected to my Azure AD a DSREGCMD /status showed the complete picture that I was truly authenticated correctly!
I signed out of the device as my LocalAdmin Account and re logged in as my Azure AD account, the login worked and my old profile showed exactly as it was! It was like I had never left(I was worried that it may create a new login profile and not reuse the old! My issue has been righted and my machine is back in working order within my Azure AD!
The problem of the upgrade unjoining the machine from Azure AD still exists but at least there is now a solution to undo the problem!
Thanks for reading and I hope you get your machine reconnected. Reach out to me @Murmanz on twitter if you need a hand!
