I get the error message shown in the attached screenshot when downloading my emails from outlook.com to a local folder called "DAD". Some messages get filtered, some not. Those that don't get filtered successfully remain in the Inbox, but a message with empty content does appear in the local folder, and cannot be deleted or moved. Re-running the message filters manually will moved the affected messages across, but the "corrupt" message remains in the target folder and cannot be deleted or moved. The drive that the folders are located on is my data drive, which has c 250gb of unused spaced. WIndows 11, Thunderbird 128.6.1 (64-bit), installed a few days ago when I moved from another machine.
