I am using Thunderbird as email client on Win 10. When trying to backup old messages I am getting en error message as below. I tried several ways exporting emails as “eml”, PDF’s or even plain text, but all the same. Following error message:


[Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getCharPref]" nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)" location: "JS frame :: chrome://mboximport/content/mboximport/utils.js :: getSubjectForHdr :: line 186" data: no]

Exporting: Folder: Inbox Msg: Undelivered Mail Returned to Sender

getSubjectForHdr@chrome://mboximport/content/mboximport/utils.js:186:26 onAfterStopRequest@chrome://mboximport/content/mboximport/exportTools.js:1809:14 onStopRequest@chrome://mboximport/content/mboximport/exportTools.js:1743:28

Can anyone assist?

This would be an ImportExportTools NG issue, not Thunderbird's. Their support site is at

https://github.com/thunderbird/import-export-tools-ng/issues

I see a couple issues that remind me of yours, so maybe it's a known problem that they're working on:

https://github.com/thunderbird/import-export-tools-ng/issues/898

and

https://github.com/thunderbird/import-export-tools-ng/issues/915

I do see one thing that you can try. Your error message mentions what looks like a message that has the subject "Undelivered Mail Returned to Sender". Maybe that messages is malformed or otherwise has something about it that ImportExportTools NG doesn't like. If you can find that message in the Inbox and delete it, then Compact the folder, maybe the export will work normally.
