I have a PC running Thunderbird email client. It accesses several email accounts. For one of those accounts something deleted the file named 'inbox' . I still have the inbox.msf.
I restored a backup inbox file from a day ago and was hoping that TB would re-fetch the day's worth of now missing incoming emails (they are still on the server). But it hasn't. It added new incoming mail to the old, but didn't fill in the gap.
How can I force it to re-fetch those emails?
And should I delete or restore the (out of sync) inbox.msf ?
