Apple Mail is Duplicating Mailboxes

Since the supplementary Update of High Sierra 10.13.3 I have had problems with Apple Mail.

1) Jamming randomly when deleting emails - gets jammed with message eg - 'moving messages 1 of 10'

2) Duplicating Mailboxes and sending email to these rather than my existing ones.

3) Attaching 'new emails' to old ones. The header and subject line from an old email and the body and text is a new email.

I would love if someone has a fix for this.

MacBook Pro with Retina display, iOS 10.3.3

Mail messages don't load on first try often, sometimes never Hi, I've had this issue with Mac Mail for months and I cannot find a solution after searching the community. This is what is happening -- when a new mail arrives, it appears in my Inbox but when I click on the email to read it, it does not load the body of the email immediately. It would take about 3-5 minutes before the body of the email appears and only after several retries. Even opening of old emails has this behavior. This is a Mac Mini with High Sierra v10.13.5. Any tips would be greatly appreciated. Thanks!

Mail stuck moving messages I have recently started to have a problem with the Mail app on my MacBook Pro with Cataline 10.15.6. It constantly says it is Moving Messages on the bottom left of the app. If new emails come through I can see them, read them, apparently delete them but although they go, when I log into my mail by another means like my iPhone the messages haven't moved. Every message I read or try to delete increases the number of messages that are moving. I have quit, force quit, restarted etc to no avail. Any ideas?

Mail content not appearing on Mac I'm having the same problem I've seen reported before: randomly, some of my email is not displaying any content on my Mac, though I can see it in iOS. I've used a work-around that one user previously described -- moving the message to another folder and then back into the Inbox, and then it seems to display properly. But this clearly seems to be a longstanding bug. Is Apple ever going to address it?
