A few of my subfolders no longer appear. For example, I have this: $ ls -h .email/Commercial/ 10 11 12 13 14 15 16 17 18 2 3 4 5 6 7 8 9 Debenu DiffPDF(c) MyCommerce Sales Support But today in the user interface I only have: .email (MH) Inbox ... Commercial DiffPDF(c) Whereas yesterday I had .email (MH) Inbox ... Commercial Debenu DiffPDF(c) MyCommerce Sales Support Claws knows that these folders are there: I tried creating Sales again and it refused. For the time being I'm creating subfolders MyCommerce2 etc., but I wish claws would find the existing folders!
Right-click the top-level mailbox folder and choose 'Check for new folders' and/or 'Rebuild folder tree'. If you can describe how this was triggered then re-open this with the description.
Thank you for your quick reply: I did "Rebuild folder tree" as you suggested and it fixed the problem.
