CCC ONE emails not working with Thunderbird

more options

Anytime I attempt to send an email in the CCC ONE application, I get this error message from CCC ONE:

"Unable to perform selected action while the email application is open. Please close your email application and try again."

This error message persists whether I do have Thunderbird open or not. I also checked Task manager while I had Thunderbird closed and found no instance of it running. Is there any way that Thunderbird is running in the background? Or could it be if Thunderbird loads at start up that it's tricking CCC into thinking it's open all the time?

I contacted CCC ONE report and they advised me to attempt to change the name of a DLL file so a new one would be created to replace it. I tried that, the issue still persists. They also told me to try and uninstall and reinstall Thunderbird, which I did, and it still won't work.

Any ideas on how to fix this?

Thunderbird does appear as a background process in windows in certain circumstances (like when there is not user interface loaded) Did you check the background processes as well as the applications in task manager.

In addition I would suggest a restart of your device. This comes back to some very old parts of multi tasking operating systems, but once a DLL is loaded and fails for some reason but does not crash it can be very hard to get it out of memory to try the next step. So restarts are part of any diagnostic process o ensure you are not still fighting an old DLL. Renaming the DLL might work, but only after a system restart is what I am saying.
