A bug that made e-mails and folders go missing for some Windows Live Hotmail users has been fixed according to Microsoft.

"We have identified the source of the issue (and) have restored e=mail access to those who were affected," the company said on the Windows Live Solution Center help site yesterday afternoon. "We recognize that even though we restored e-mail access, some of the affected users did not receive mail sent to them during the last 24 to 72 hours."

Microsoft says the issue was fixed early this morning, although if users are still having issues, they should send in a help request using a specialized form.
