I raised this issue earlier and Agnes responded. However, the response did not solve my problem, which I do not blame anyone for. I would like to provide some more information which might contribute to a solution: Earlier this year as the result of an IMAP server problem, I lost some mail that should have been saved in local folders but weren't. I have used TB for many years but due to my unfamiliarity with directories and file structures, I subsequently relied on the services of an online IT expert to help retrieving the mail from a previously saved profile. Somehow he copied and pasted the folders and data into the directory Mail/Local Folder/Archive.sbd/TEMP.sbd. Archive and TEMP folders both contain the same .msf folders, which is a bit weird! However, while whatever he did works on the "old" laptop, it doesn't work on the new. I can see the TEMP folder and data in the profile copied to the new TB installation, and the conundrum now is to figure out how to open it in TB on the new laptop? I tried to upload a screenshot of the relevant directory and .msf files, unfortunately the process is very slow, so I have abandoned the idea for now. Can anyone else offer some guidance?

Thanks in anticipation, John
