I have used Thunderbird for a very long time. Currently on my desktop it is no longer receiving messages. Also when I go to send an email I get the following message. '''Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders Sent-!!!!!!!!!!!!!!. '''(The exclamation points is where my email address would be) The email goes out but it is not saved locally. On my laptop Thunderbird works just fine receiving both emails and sending emails. No problems there. Both systems are configured the same with firewall and antivirus (ESET). Both Thunderbird programs are also set to the identical settings for both the security and server settings. Anyone have any thoughts on what I need to do. I have never experienced this issue before.
