Hi everyone. I am stuck with a very particular issue that probably never happened to anyone. By mistake I've deleted all the certificates in the window you can see in the image. Basically I selected each server and then "Delete". I have 5 Gmail accounts and 3 other emails accounts from other domains configured on my Thunderbird and all stopped working since then. Can you help me to restore the certificates or disable some security checking in order to get the email working again? Currently I am not getting any email box working. Thanks in advance! P.S. - The image in attach is for reference only, it is not my screenshot. Since my Thunderbird is not in English I've assumed it will be better for you to understand.
