Today every time I open my e-mail account I get the following error message: "The folder Inbox on (my zoominternet e-mail address) 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." Never seen this error message before today. What should I do to get rid of it or correct the problem? I am receiving e-mails, but I haven't tried to send any. Thank you.
