Sent emails not saving to "sent" folder, only with most recent upgrade to Thunderbird.

Thunderbird 疑难解答

I am using Thunderbird 102.3.0 on Win 11 PC.

Only after applying a recent update, am I getting the "Your message was sent but a copy was not placed in your sent folder (Sent Mail) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent...etc" message.

My account is set up as IMAP with Westnet (though I can't see the incoming server settings in the new Thunderbird any more?) but those sent items are not being updated on their server either (I have checked by logging into webmail) or they would eventually appear in my Thunderbird account Sent folder.

My Copies and Folders settings have always been "Place a copy in "Sent folder on myemail@westnet.com.au". The alternative option is "Other - Sent on myemail@westnet.com.au". I don't know what the difference is? I don't want things stored only locally as I access my email on several devices.

I went back to an old version of Thunderbird and the issue went away. But I didn't stop it automatically updating so now I am back to having the issue.

This is serious enough that I will need to change to another app rather than lose my record of sent emails.

Any clues? Thanks.

I have this issue, too, but only with one account out of four. Like the original poster, I too am considering using another email program if this issue isn't resolved. This account has another issue but I'll post that elsewhere so this thread stays focused on the same issue.

I had the same problem with sent mail and one other problem. A fellow named David gave me a workaround that worked for me. You'll find the thread here:
