Hello! I have two Gmail addresses, the main one [A] with very little space left, and a second, new one [B] almost empty where I'd like to archive a lot of the first address's emails and label them. I add them both to Thunderbird and subscribe to all folders, including "All Mail" and all labels/sub-folders. My process is to select a mail in the "All Mail" folder of [A], then move it (not copy) straight up into a label folder of [B]. This way, the mail doesn't exist anymore in [A], and only exists in [B], all of this done in one simple & quick operation. After a few tryouts, I realize that if I use "Move To", or if I drag an drop an email from A to B, the mail is actually copied into B and still stays in A. I then have to delete it from A manually. Is there any procedure that will allow me to cut/paste emails more easily between both accounts? Thank you greatly, all! :-)
