Thunderbird 3: sent messages disappeared

jankomax

Hi all,

I had a big problem when upgraded from Thunderbird 2 to version 3 a few days ago: the sent messages disappeared completely.
At this moment, inbox messages have a size of 4GB , this is OK, but trash is also 4GB, very strange.
I tried to delete msf files and started Thunderbird again in order to generate new msf files, there was no change.
What do you suggest me to do? different actions which I can do are appreciated in order to solve this problem.

Many thanks in advance for your help.

Some more info, I hope someone can help me.

POP or IMAP type account? POP.
Have you determined if the missing Sent messages are in the Trash folder? I can not open trash folder, when trying to access, I get blocked. The size of trash folder is of about 4,3 GB.
Is the Sent folder still displayed but empty? The situation is the following: I had Sent folder and inside it some subfolders with some e-mails inside them, but most of the sent e-mails were not in subfolders. The fact is that the subfolders with their e-mails are displayed whereas those e-mails that were not in subfolders have disappeared.
The problem with Thunderbird 3 took place when taking a look at profile folders, a crash file was generated.
What is the target for the Sent folder under Tools->Account Settings->Copies & Folders? Its target is "Sent", so having a trash of such large size seems to be due to the crash of TB3.

Many thanks.
