Thunderbird hangs while downloading new messages

How to Fix Thunderbird hangs while downloading new messages?

I get a big gap and whenever a message gets downloaded, Thunderbird freezes, which can prevent you from writing your email. Once the download is finished, it will start back in general and whatever you wrote That’s all it will appear at once. So whatever you type while downloading Thunderbird, it is not lost; This download does not appear on the screen until it’s over, about 15-20 seconds later.

I have tried to change webmail and Thunderbird download frequency settings. I have tried to start TB with add-on disabled, I have not tried to rebuild files or anything like that, but whatever I have read, he says that he has not made any difference. This problem is directly linked to the new mail being downloaded in TB, every time a new email arrives.

Sometimes a message download session may be interrupted using POP3 before downloading all messages to the server due to problems on the POP3 service. Thunderbird gets bogus after fixing the problem. It is hanging if I do not remove the last message downloaded from the server during the interrupted session. It displays the position line Getting message 1 of XXX and just hanging out. No matter at times I’ll try, as long as I manually deleted the last downloaded. In some cases, the problem may be due to the mail summary file (* .msf) being corrupted by the file, this can happen when your folder becomes slightly corrupted because it is not compacted regularly.

  1. Exit Thunderbird.
  2. Find your profile folder.
  3. Open the folder which contains your stored messages. For example, if you are using Global Inbox, it will be a “Local Folder” folder inside the “Mail” folder. Otherwise, it is a folder on the name of the mail server inside the “Mail” folder. For example, if you’re using Gmail, “”
  4. Select the *.msf files and delete them.
  5. Again Restart Thunderbird.
  6. Wait for Thunderbird to recreate the mail summary file.

If that does not work, it may be because your folder is very badly corrupted. In the Compacting Folders, see the second part of “Compacting does not work” If there is a problem sending a message, try reconfiguring your anti-virus program so that it does not check outgoing messages for viruses. In some cases, the problem occurs when Thunderbird has trouble finding and filtering junk (SPAM). This may be due to a corrupt training.dat file, it may be necessary to remove it (run on Tools -> Options -> Privacy -> Junk -> Reset Training Data -> OK) and [Mail Control] .
