My sent folder in one of my email accounts in Thunderbird was emptied completely when I was tring to delete older emails. Fortunately I had archived the complete account a few days previously.
Now I wish to restore it. Of the various archives, that is the only one whose name is not prefixed with ‘Thunderbird’ - I don’t know why. If I highlight an email and click on the ‘Restore to Thunderbird’ button I am eventually offered a series of target folders including ‘Sent 1’ (which does not exist). The existing folders are all greyed out. I select, click on OK, get a messsage that the email has been restored, but I don’t find it anywhere, nor any folder named ‘Sent 1’. This is a MAPI account - is that the reason? How can I restore the entire archive?
