Inbox messages disappeared and were not loading for about 1 hour prior to them disappearing. I can view emails on Dream Host Webmail as well. That is how I know that emails have not been loading onto Thunderbird. Can still view all other folders. Sent, drafts.......... Was getting an error message initially that another operation was preventing the inbox from working as intended and to wait until that operation was finished. I do not know what that operation is. I now no longer get the error message - just no new emails in the inbox. How do I get inbox messages to return?
