Had an interesting experience where a user had created several peer folders to the Inbox, that had leading '/' in the names. Afterwards, they absolutely could not delete them via the SWA or IMAP. I looked at the folder structure with omcontain and found that the server had created a 0-character folder as a parent for the folders with leading '/'s, and removing that resolved the issue.
So - to keep from having to delete folders every week, is there any way to require a minimum character length (1?) for folder names, or maybe just not allow 0 byte folder names?
Thanks,
John
