I can't login anymore to Teams desktop application

Question

Hi, I haven't managed to login to the desktop application since last week. I get the issue caa70004.
With the same computer I manage to login to the web application without any problem.

I have tried the following :
clear the cache files of the teams app,
execute with admin privileges
new install

I get always the same issue.
Could you help me please ?

Hi @Gil TSSR

Does anyone else have the same problem in your organization?

In this way, we recommend you try to run Microsoft Teams using compatibility mode:

• Right-click on the program or program shortcut icon and select Properties.
• Select the Compatibility tab
• From the Compatibility mode section, check in the Run this program in compatibility mode for
• From the drop-down menu, select the version of Windows in which you knew this program to work.
• If you are running Windows 10, select an earlier Windows version, on which the program ran well.
• Click Apply > OK.

Meanwhile, if you are using VPN connection, please also try to disable it to see if it works.
