I have created a "master" subfolder (e.g.: "Yearly ALL") in my email account. As 2020 approaches, I want to copy the entire subfolder and all the subfolders beneath the "master" subfolder to a 2019 archive folder (e.g.: "2019_in"). What is the easiest method to copy, yes copy, the entire master subfolder "Yearly ALL" to be a subfolder within my Archive, within "2019_in"? I surmise by copying. I'll have two sets of identical messages. Then after the "copy" is successful, I can empty each subfolder. Likewise, by using a "move" or drag & drop I would need to create all new subfolders and reenter all my rules, about 60. Below is my master subfolder with about 3.000 messages in all the subfolders which go down about four levels.. Thanks.
