At least 10 times a day, I'm receiving duplicate emails that were originally downloaded that morning or even a day or two before. I've tried deleting the popstat file. I've downloaded the 'remove duplicate email' add-on and i have verified my anti-virus doesn't scan email. I'm about to uninstall the program and say forget it. I remove anywhere between 300-500 duplicate emails per day and generally have to compress 3-4 times daily. I use this for work emails, and important emails are being lost in the duplicates...

First check this and set Thunderbird to delete messages from the server: go to "Tools -> Account Settings -> Server settings", and uncheck "Leave messages on server."

If not you could also try Compacting the Mail folders or Compact folders, exit Thunderbird, and go to your mail folders (in your profile folder). Delete the index files, named "*.msf" (such as "Inbox.msf"). These will be rebuilt when your launch the application again.

What type of email account do you have setup? POP or IMAP?

it's a pop account

There is a file in your profile (Mail subfolder, then the subfolder for this mail account) called popstate.dat. It contains the information about which messages have been downloaded from the server. Possibly your popstate.dat file has been corrupted. Exit ThunderBird, find and delete (or rename) the popstate.dat file for that mail account, restart ThunderBird. It will download all messages residing on the server one more time, but should download only new messages after that.

Where to find your profile: http://kb.mozillazine.org/Profile_folder

i have deleted that file twice this morning and just renamed it. I'm now downloading 129 emails, all of which are duplicates. Some were received as far back as a week ago.

I think that may have solved it! I was trying to keep my emails on the server just 'in case', but now that I've changed that setting, I'm not getting the duplicates anymore. Thank you so much
