Mail slow in moving messages
I have MacBook Air (2022) with the latest software Sonoma v 14.2.1 and find that moving messages in mail (whether deleting or moving to another folder) is really slow going. Messages that were moving got piled up in the hundreds, with nothing moving at all (i.e., stuck at message 1 trying to move 1 of xxx). I tried re-booting, rebuilding inbox, restarting mail..nothing worked. The only thing that helped somewhat was to delete the mail account, and then add it back in. It at least eliminated the hundreds of messages to be moved, but it is still extremely slow to move messages (even when it's 10 or less). It does seem to finally get them moved if you let it sit for an extended time (20 min to an hour depending on # of messages being moved). I've read one person say you should not move a large number of messages at once. That's a crazy solution, and tells me this still needs a fix from Apple.
