I upgraded my system from Ubuntu 18.04 to 20.04 and as part of that, cyrus-imap was upgraded to 3.0.13-5.
Unfortunately, all users lost their folder subscriptions and thus, the subfolders to not appear in their email clients anymore.
Do you have a hint for me how I can set "subscribed" to all folders in all Mailboxes of all users? It seems a lot less work to unsubscribe all unwanted folders now than to subscribe to all folders again...
