Yup, did that, but never hurts to remind to do backup, thanks.

I did try this, although this is a subfolder with a space in it, so not 
sure it worked so well. The folder is "user.roozbeh.Papers.Category 
Paper" I tried "reconstruct roozbeh.Papers", and it did its thing, and 
didn't complain, but the folder still isn't there. I wasn't sure how to 
deal with the space, so I tried "reconstruct roozbeh.Papers.Category\ 
Paper", and got Mailbox does not exist. I tried "reconstruct 
user.roozbeh.Papers.Category Paper" and got usage: reconstruct [-r] mailbox.

We were having problems with accessing this mailbox before it 
disappeared (he was able to see inside, and look at the emails, but not 
move any in or out), and at that time, we tried renaming it and moving 
it, and nothing worked. Sometime after that I moved the cyrus directory 
to a new hard drive, and when I mounted it again, I think that is when 
cyrus lost track of the folder entirely. I just tried creating the 
folder with cyradmn, and it appears to have created it, but I can't tell 
if it is empty. Is there a way to tell using cyradm if there is mail in 
a folder? Obviously, I can and will ask the user, but curious if there 
is a way to do it from cyradm. The contents of the folder still apeaar 
intact on the hard drive.

nope, well, now it is. :-)

thanks for your help. I'll let you know if this worked.
