Or, scores of the exact same messages... Thunderbird 93.0b2 (64-bit) Windows 10 A few days ago I went to look for a message in a local folder I created to move messages to that are important, that need to be saved or that I need to attend to and discovered that an entire year's worth of messages has disappeared or that the message header is correct but that the message body is not. Or that I have scores of the same message and header. In fact, there are scores of emailed reciepts from a record company in the place of pretty important messages. that receipt, btw, was moved to that folder months and months ago. I tried to "repair" the folder and that did not work so I shut down TB, deleted the appropriate, MSF file and when I came back it was actually worse than before. Right now there are more than 300 messages in that folder which should all be different with almost 300 exactly the same, headers and all. What's going on here? The Message file for that folder is 42 meg and the recreated MSF file is 97kb... something isn't right.
