Thanks Kevind! Since you're not seeing any IDS blocks, can you check the Error logs to see if you see any entries noting this user account? I suspect they may have a corrupt folders.json or folders-xxxx.json. Worst case though you should be able to restore a backup copy of the bad file from the user's Archived Data folder if that is the case. 

Hello, 

Looking at the exception "Path: con." I think this user has a reserved folder name for one of their folders. Can you review the folders and see if this is there. If this is there you will want to remove it from the users folders.json file. 

stop the service 

edit the file

save

start the service back up. 

Thank you

@Kyle, we restored a backup file of folders.json and that didn't make any difference.

@Tony, yes, there was a "con. calls" folder listed in folders.json, but that didn't exist in the folder structure. So we will remove it from the .json file. Is there any way to get it to take effect without stopping/starting the service?

Thanks!
