Upgrading from 2.4.17 to 2.5.3 resulted in one very strange problem. Some of the users have a large number of nested mail folders. After the upgrade, exactly one user found that some of his folders (say 3 out of 30) are now inaccessible. In Thunderbird they show up, but are greyed out. If you try to subscribe to the folder, the subscribe checkbox is missing. In roundcube they aren't visible at all. This is pretty clearly a permissions problem of some kind. The question is how could this happen and what's the least painless way of going about resetting the permissions so that he has access to these folders again? We're not doing anything fancy; for example, there are no shared folders; independent email addresses are configured for shared mail content and configured in the MUA. The problem folders are in an unshared account. Also, the manifestation of the permissions problem isn't consistent across the affected folders. As reported by the user: Archives Staff: grayed out, cannot see email Archives Staff Retreat: not grayed out, cannot see email, when you click on it, it says the action cannot be completed because the account does not exist General Convention Office: not grayed out, can see email, when you click on it, it says the action cannot be completed because the account does not exist.
