I can see all sub-folder in my inbox but one

[rnb]

I have a folder named "2. Support" and I have created a rule to send all the emails to this sub-folder from a group.
I have created similar sub-folders for other groups.
They are all visible, but this sub-folder.

I have tried to recreate it, to check if it was deleted by mistake, and I got the following error

An error has occurred. Contact your e-mail administrator if the problem persists. #CMD017

Most probably to tell me that this sub-folder already exist, but I cannot see it. I can see all the other sub-folders, but this one.

Any help?

run this script

[rnb]

Just took me couple of minutes to put the script in a file and execute it.

It has been years since my Unix days, just getting refreshed on the those scripts

Thanks a lot.
