It's odd. I right click on an email to invoke the dropdown options, and selecting the Move to . . .. and then selecting one of my 4 accounts, it usually reveals all my folders. But now it's showing only 26 of the 29 alphabetized folders, skipping the three I have labeled starting with the word "Travel." Now why on earth would that be? Of course, I can click and drag them there, but is there some explanation in case something like this continues to happen?
