When a user has a large number of top-level folders (over 100, I think), instead of displaying them all in the folder list, Zimbra shows "Show remaining folders" at the bottom of the list. Normally, you can click that text and the rest of the folders will display. I have one user for whom this doesn't work. You click "Show remaining folders" and nothing happens. For other users, this works properly, so it's not a general problem, but something about this one account.
I can use "zmmailbox gaf" to list all his folders, and they look fine there. Has anyone else seen this? How can I troubleshoot it?
