Recieving error "Index entry has too many levels"

I have a user who is receiving the error “Index Entry has too many levels” when opening folders in her local mail replica. This is not consistent and happens at random times in random folders. She does have a ridiculous amount of folders, but I can’t find any explanation of what the error is telling me so that I can troubleshoot effectively. Has anyone seen this or know what this is trying to tell me??

Thanks!

sounds like maybe a folder has too many netsed levels. Not sure what the limit is off hand. Also a folder name cannot be more than 256 characters, if my memory serves me correctly. Open Folder list in designer and check for long folder names.
