The folder 'Outbox on Local Folders' error "could not be compacted because writing to the folder failed."

Thunderbird Send and receive email

For the past week or so, I've been getting the following message every time I open Thunderbird.

"The folder 'Outbox on Local Folders' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

Also, the folders appear to be empty, but the eventually repopulate. I have plenty of disk space and haven't changed write privileges. A Google search doesn't turn up any solutions. Can anyone help?

Do you have an antivirus program other than Microsoft defender? Generally anti virus programs scanning the contents of the Thunderbird profile folders while the program is running causes issue like you describe.

Thanks, Matt. I tried that and it didn't seem to help.

Kenneth, does this work for you with the most recent version of 128?
