Hello, and thank you for using this service.
Sorry to hear you are having trouble. I will help you now.
Would you like for me to make a remote connection to your computer to fix the problem with Thunderbird? NOTE: There is an additional fee for remote services, but it's faster, easier , and more effective at solving problems like this.
No, the issue is we can quickly see the error messages, problems, settings, and so on to work on solving the problem.
what is the exact error message you are receiving?
