Moving Mail items

I started getting the error message below when trying to move certain emails from the In Box to another folder, or when deleting emails. Doesn't happen with all emails, just some. And then later I may be able to more or delete the problem email. I have a MacBook and I also just upgraded to macOS High Sierra. Haven't had this problem before. Any ideas?

"The IMAP command "UID COPY" (to (name of folder)) failed for the mailbox "IN BOX" with the server error: UID COPY Command is not valid in this state."

Yahoo! Mail?

Yahoo acknowledged a bug exists on their systems and is allegedly working on a fix to be implemented by the end of this week.
