IMAP Folder Errors -- Error type: RENAME failed: RENAME failed: Invalid argument

[Pondboss]

Using Zimbra Desktop 7.2.1.
I'm getting many sync errors, perhaps during application of filtering rules, for sub folders. All folders were created on remote host via remote host's webmail (Horde). I originally had the same problem with folders created directly in Zimbra Desktop (which I then deleted, and let them be created via sync with the remote host IMAP server.) Seemingly there is an error renaming the folder from caps INBOX.* to Inbox.*
Here is the a sample error message:

I suffer a similar fate today. New install, made additional folders and moved all mail to these folders. One hour later, the folders are gone along with the contents and I had 40 error report messages like below.
