Have used Thunderbird for many years without problem but today: 1. Thunderbird asked to compact Inbox folder said OK 2. After Compacting appear to have lost all emails back to 24th Jan 2023 emails prior to that date are OK) 3. Emails which had arrived today are shown with subject and time but on opening they are blank except for message ----=_NextPart_000_00BC_01D6069F.D8AB25B0- 4. Messages which came in after compacting were OK and readable. 5. Following comments previously made tried inbox/properties/repair folder. 6. Following attempted repair messages that were readable at 4. above were now blank except for the message "Next part...." as in 3 above. A. Can I recover my lost emails? B How do I prevent Thunderbird from corrupting new emails when it compacts folder? Cheers Keith keith@castlemurray.com.au
