Archiving emails to Local Folders is not working for me. If I click the archive icon or press 'A', a new folder is created as required in my Local Folders/Archives, e.g. [Gmail]/Important. But the original email does not move, no emails are shown in my Local Folders nor do they seem to exist in the folders or files created: [Gmail], [Gmail.sbd], Important (empty) and Important.msf. I have picked up that I need to set archiving options by identity as well as by account. The problem remains the same whichever IMAP account, which is Gmail and another smaller provider, or identity I use. Before I realised that, archiving did work - in terms of emails being moved to an archive folder within an IMAP account. But I want to download the emails locally to avoid going over provider storage limits. I've checked and Thunderbird can otherwise create new messages in Local Folders, e.g. when my network connection is interrupted it saves drafts there. I'm using Thunderbird 115.11.0 on Ubuntu 24.04 / Wayland, and it's installed as a snap. Many thanks in advance for any help you can provide!
