Have a user in a business environment in Peer to peer, getting the following error:
microsoft teams won't allow the user to sign in, getting error code caa70004

 

Teams is currently the free version, so finding support for this is next to impossible.   The app just wants to Restart, and goes no where but the error code.   Local users, not on O365, but the users account can log in on office.com.

Any help would be appreciated.   And no, have not just done the uninstall/re-install, yet.

Thanks,

Dave

@adam deltinger, hmm.   Tried that script, came up with a couple of errors, then seemed to run.  But the same issue.  So I'm thinking maybe the info didn't clear out.
I'm just going to see what happens with uninstalling and re-installing the app.

Hello,I met the same problem as you, did you resolve it by reinstalling the Teams?

@DHuttema We had this same issue today with teams installed on one of our machines, it turned out the TLS was switched off in Internet Explorer. Turning this back on resolved this issue for us.

 

  1. Open Internet Explorer.
  2. Go to the Tools menu.
  3. Select Internet Options.
  4. Select the Advanced tab and scroll down to the Security section.
  5. Check to see if you have TLS 1.1 enabled, TLS 1.2 enabled (checked).  If not, check the box to enable it.
  6. Select OK.
  7. Close Internet Explorer
