I am not able to share a briefcase with fellow users under an account. This briefcase has subfolders and the share is completed without errors and 'only' with the root folder. Subfolders are not shared with it, or not seen under the share. View right was granted.

I decided to test this feature with my account and surprisingly it worked flawlessly under mine. I was able to share a briefcase that structured the same way as the one in question. So I am thinking if some message or content in this folder is corrupted or if there is any problem with this account. Can anyone help to carry out tests on this folder?

Tried mounting with zmmailbox command too, but same results.

There is no error in mailbox.log when this happens. Please shed some light.
