I have a similar problem, except this is where the folder does exists, doesn't let you create one with that name, and is associated with e-mails when you perform a search.
Basically, the run-down of my scenario is:
1. User says, "Hey, where's my Stoneridge folder?"
2. I tried to re-create it, and it says it already exists!
3. I look, and it's not there.
4. I try to add it, and it indeed claims to already exist.
5. I find this thread on how address books and calendars can affect this.
6. There are no address books nor calendars with that name.
7. I re-index the mailbox.
8. Still no folder displayed.
9. Do a search where content = 'stoneridge' and I get e-mail hits that claim they are inside the "Stoneridge" folder. ...
10. Commence scratching of the head.
Anyone have any ideas? Where does zimbra pull the e-mail folder list? The folder is obviously there, but no interface can display it.
The advanced search 'folder' tab doesn't show it (by the way, this user has so many folders that there is a "Show remaining folders" option which doesn't work, and checking the checkbox next to it results in an error)
Hmm, y'know...maybe this is coincidence, but the folder that is missing seems to be between "STI..." and "Stors...", and "STI..." is the last folder displayed until I click on that plus sign. I'm going to add another folder, to see if "STI..." disappears, and possibly shows the hidden folder....
Yup. (I had to log out and log back in) that is indeed what is happening. I now see "Stoneridge" and no longer the "STI..."
Anyway...how often do you get a problem + work-around in the same post?
EDIT: We're running ZCS NE 5.0.8
