Am a long time user of Thunderbird and I received error msg: "Unable to write to the mail box, make sure the file system allows you write priviliges, and you have enough disk space to copy the mail box." I can't figure out how to do this. I finally deleted my account and reinstalled Thunderbird and continue to receive this error message. I can't receive and new message on my computer and using gmail on my phone. my email is rstoma@astound.net. Thanking anyone in advance
