Dear Support Team, I recently recovered a disk from an older laptop and successfully exported all messages to my new system running macOS X Monterey (12.7.6). The installation was done from scratch, without having Thunderbird installed previously. I am currently using Thunderbird 128.7.1esr (64-bit). However, I am encountering an issue where all messages—whether old or new—are appearing in the same month, despite the actual date they were sent. When sorting by date, the inbox sorts correctly, but all messages display with the same month (April), regardless of when they were received. This issue occurs across all folders (Inbox, Sent, Drafts, Archives, and any local folders). While the day and year are accurate, the month always shows as April. I have verified the date and time settings on macOS, which are set to automatic, and the region matches the settings in Thunderbird. I have also run the "Repair Folder" option on the Inbox folder properties, but the issue persists across all folders. Do you have any suggestions for resolving this? Thank you in advance for your assistance! Best regards,
