I don't know what an Sbd file is. How did you back up the profile?

Hi David Not sure how I saved them as such, I followed the instructions of a 'tech expert', but I think it was using the thunderbird export menu, although it does not look familiar when I tried today. I searched for what is an SBD. file and this is what I found

'.sbd is not a file. It is a directory where your downloaded email messages are stored in files. Each file in that directory represents an e-mail sub directory ie. Inbox, Sent or Drafts ... etc.

Each e-mail account you configure in Thunderbird will have its own .sbd directory.'

I tried Importing from this folder but I was unable to do anything. thanks for your reply.

Okay, it sounds like the person just copied your old mail message folder, as thunderbird does have sbd folders. Since you changed email providers, I suggest you start over, creating an account with new provider. To salvage that sbd folder, you can try this: - exit thunderbird - locate your local folders folder in the profile. That is at c:\users\<yourid>\appdata\roaming\thunderbird\<yourprofilename>\Mail\Local Folders - copy the sbd folder there and restart thunderbird. the folder may now be visible.

Thanks David. I have just looked there and the profile was updated today so it may be too late to restore the lost profile. I do have data in the original SBD file I just dont know how to get it back into Thunderbird. Using a third party program I have managed to save it as a PST file but can only open this in Outlook. Can i import this to Thunderbird? thanks again.

My earlier response explained how to get it back into Thunderbird.
