The IMAP command “UID COPY” (to Trash) failed for the mailbox “INBOX” with server error: UID COPY Command is not valid in this state.

When I am attempting to delete emails from iMac mail app, a yahoo account, all other gmail accounts work, only yahoo, the following warning comes up. "The IMAP command “UID COPY” (to Trash) failed for the mailbox “INBOX” with server error: UID COPY Command is not valid in this state."

I am not able to delete my yahoo emails from the mail app. I can delete if I open up and delete them from my iPad or iPhone, but it is inconvenient. Does anyone have a fix to this? I have deleted and reconnected the mailbox to the mail application. Any help would be greatly appreciated.

iMac (Retina 4K, 21.5-inch, 2017), macOS High Sierra (10.13)

Go to your > Mail Preferences, > Accounts (select your Yahoo account since this issue is only affecting Yahoo Mail), > Mailbox Behaviors - then under Trash Mailbox, select NONE.

Hello beav32992,

Thank you for using Apple Support Communities.

I see that you are getting an error message when trying to delete email from your Yahoo account via the Mail app. I was able to find the following extended thread on the Yahoo support forums: https://forums.yahoo.net/t5/Temporary-Errors/I-can-t-delete-my-emails-from-third -party-email-apps/td-p/327030

Looking at the thread, it appears that the Yahoo engineering team has identified the issue and is currently working on a fix, per the Accepted Solution from a Yahoo staff member: "Hi everyone. Our engineering team has found the cause of the issue and is working on a fix. It seems MacMail's code changed with the new OS update and we just need to make sure our servers respond correctly to the change."

Best regards.

Change message status to "read." Then it seems to let you delete.

Hope this helps.

Just had one refuse to delete even when listed as "read" so that's not a full solution. Hopefully Yahoo! will fix this soon.

I had the same issue, I ended up reformatting the drive and installed osX 10.11 El Capitan and everything works. I’m waiting to see if Yahoo or Apple are going to take ownership on the bug 🐜.
