Mage cannot copy one folder in one mailbox

QMM 8.14

MailSync (Mage) is getting hung up on a specific folder in one mailbox. I found a sub folder below this Cardiology folder that had an invalid character in the name, and had the user rename it. Still getting the same error. Can't find anything on it in the KB. Below is an excerpt from the agent log showing the error.
