Error caa5009d

Question

We keep getting the error caa5009d happen at random on some of our machines. I have not been able to tie it down to one specific cause. 1 instance is the user changed their email password, and then the next time teams loaded the error happened. For information we have a separate active directory infrastructure, from where our Office 365/Teams is running. There are no links from the domain that the machines use to Azure AD on the Office 365 tennet. I have logs from machines that’s its happened on. It can be fixed by deleting the user profile in some instances, others deleting the teams folder from the user profile, and the re-loading it has worked. Other times that has failed and a new profile is required. If anyone can help with this error that would be great! Thanks! Richard

Answer 1

so it seems like that adding the Microsoft account in settings.... accounts... access work or school. Then clicking connect and entering the email address that you use with Teams seems to resolve the issue.

Answer 2

• Navigate to: https://apps.microsoft.com/detail/9nblggh4nns1?hl=en-us&gl=US
  • this will open the microsoft store and should present an option to either Get or Update the App Installer component
• Once the install or update of the component is complete, navigate to: https://www.microsoft.com/en-us/microsoft-teams/download-app
• Download and run the installer

Answer 3

This worked for me.
Used https://store.rg-adguard.net/ to generate the link for direct download of the MS Application Installer package. (latest version at the time was Microsoft.DesktopAppInstaller_2023.1215.611.0_neutral_~8wekyb3d8bbwe.msixbundle)
Downloaded latest teams installer from https://www.microsoft.com/en-us/microsoft-teams/download-app (filename MSTeams-x64.msix)
Used PowerShell run as admin and entered 'add-appxpackage -path directory\path\to\Microsoft.DesktopAppInstaller_2023.1215.611.0_neutral~_8wekyb3d8bbwe.msixbundle' to install the latest version of desktop installer downloaded.
Then the MSTeams-x64.msix file just needed to be double clicked to install the version downloaded.

Answer 4

I got the same error and I was very surprised because this is brand new laptop, I just installed office 365 from portal.office.com, then I downloaded teams and ... it failed to install. There isn't old teams configuration to cause problems nor any other problems with the laptop. Just a new laptop, new windows and ... typical Microsoft.

Answer 5

The solution that worked for me was to Update the Microsoft App Installer through the Microsoft Store. It needed an update. After that, Teams For Business installed fine.
