Help for theese message!

Hello, someone can help me, I get this message all the time:

[IMAP] Failed to open folder “/ Archive / Inbox / 2020-06”. (NO SELECT Mailbox does not exist)

What should I do?

Thank you all.

One thing you can try is to right-click on the Archive folder and choose Properties > Repair.
This will re-sync the folder with the server.

See if you still get the error after that.

Hello and thanks for your reply. I tried to do what you told me but it keeps giving me the error. When I try to repair the archive folder, I don’t see any particular changes.
