Hello, I have never used Thunderbird previously. May I ask a newb question? I can longer export my emails from my main online email account in the form of a file for back up. That would be an Outlook/Hotmail account. That is not the only scam Microsoft have pulled in the last few years with Outlook as well, which I am more than happy to go into if asked. I do not want to, nor can I install their Desktop Outlook app which I understand still allows export. So my question is, if I install Thunderbird, does in sync with another email account, then download and store them on PC for back up? It would be many thousands of emails as well. The file exported from Outlook until Microsoft inflicted their latest used to be around 12Gb. Also, if I do anything via thunderbird, is that replicated in my Outlook email account? I am concerned that emails may disappear from the email account if say Thunderbird is removed from the PC. Any advice or pointers to already existing thread would be greatly appreciated. Thanks. Mike.
