Hi everyone, It's one of those questions that gets asked out of pure fear of the unknown. I installed the latest version of Thunderbird on a Mac, logged in with an Outlook account with all the default settings. As soon as the application began to copy/download e-mails from the server side to the local storage, I realized I was pretty low on storage, so I closed TB immediately to halt the process. Bottom line is: how do I uninstall Thunderbird completely from a mac without it affecting all the e-mails on the Outlook webmail (server side)? In other words, I just want to return to the state of things as they were before I logged into Outlook on Thunderbird. I sent a test e-mail and deleted it on Thunderbird and it also got deleted on the webmail used on the browser (I guess that is a sync feature of IMAP?). So now there's a rounding fear that if I mess enough with Thunderbird I might make a big mistake. What's the correct procedure to leave everything as it is on the server side and get rid of Thunderbird (at least for now)? I was thinking of turning off the WiFi and then deleting the application. Does that make any sense? Or should I delete (or log out?) the e-mail account from TB and then delete the software? Are there any folders or sub-folders that I should take into account after deleting TB? I mean folders that store e-mails/attachments/large-file-sizes that are eating up local space that I can also get rid of without any second thoughts. Any help would be greatly appreciated.
