I have an email account set to download ONLY headers, because it gets a lot of spam/viruses. However, I now have a lot of historical records that only the headers were downloaded for and I now want to download the full message .... for all of them at once (it is super slow to have to interact with each one individually). I searched help & searched the forum, but get a ton of hits that don't address my problem. Is there a way in Thunderbird (I have the latest release) to select a group of messages that are headers-only and have their bodies ALL downloaded at the same time? Thanks!
