Thunderbird sometimes re-downloads old messages











up vote

I have configured Thunderbird to download messages through pop3 and I must leave a copy of the messages on the server inbox, so I cannot delete them from the provider.



Sometimes (1 - 2 times per year) it happens that Thunderbird starts to download all the messages as if they hadn't been never downloaded.



How does Thunderbird keep track of already downloaded messages? Is there any way to avoid this messy situation?



Someone suggests to move the messages from the Inbox to an another folder but unfortunately the tools provided make this operation very time wasting.

Must is a pretty strong word. Why?




Thunderbird starts to download all the messages as if they hadn't been never downloaded.




Possible reasons: popstate.dat file corrupted, popstate.dat file deleted, uid roll (where the server changes the unique email identifier)




How does Thunderbird keep track of already downloaded messages?




I suspect something like CCleaner is deleting your popstate.dat file https://stackoverflow.com/questions/318673/where-does-thunderbird-store-the-uid-of-the-last-message-downloaded-via-pop file

  • Thanks for your answer.1)must because multiple workstations uses the same account and the customer wants to leave a copy always online. 2)I don't think an UID roll (other workstations would have been affected as well) but probably the popstate.dat got corrupted. Thank you for the hints! Any way to hack the popstate.dat or tell thunderbird please stop download email dated before a particular date? Bye

  • In most cases where multiple people must access an account, imap is a better model then pop. Further, keeping all messages online is not a great practice for pop accounts.
