Hello readers,
A few days ago the Microsoft Network Email System automatically deleted my email account. This happened because there is a bug in the Microsoft Network Email System that may unintentionally remove email accounts without prompting. I have included a patch with this email that will fix the bug on un-patched computers. If you need help installing this file, read attached help file.
Thanks.
