Get this error message I think since the update on September 2nd. See below

Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox. Also, I downloads a few old emails from September 2. If I delete them, they re-download when I click on get mail. I do get mail on my phone and on the Xfinity web site. I really would like to get this fixed as soon as I can. Thanks, William Dudzinski - <redacted>@comcast.net - <redacted>
