With the recent upgrade, I can no longer move emails between folders, by any method. Tbird 52.3, Mac OS 10.10.5
Previously, I've been able to move messages by drag and drop or the Messages menu to other mail account folders. I usually needed to do this because the email arrived in a spam folder. Now most emails are in the spam folder and I can't move them.

In the Junk folder? If so, you should be marking them as "Not Junk", not moving them. https://support.mozilla.org/en-US/kb/thunderbird-and-junk-spam-messages#w_training-the-junk-filter
