Microsoft has apologised for the recent technical snag that had hit 17,335 Hotmail users on 30 December, deleting every single e-mail from their inboxes.
In a blog post, Microsoft's Corporate vice president for Windows Live Chris Jones said that the company had discovered the flaw and restored the deleted e-mails, but failed to explain the root cause behind the error.
On December 30, disgruntled Hotmail users had taken to social networking platforms Facebook and Twitter to voice their frustration over the unexplained flaw.
Many of the users had reported that when they accessed their Hotmail accounts, every single e-mail stored on their account had simply vanished with only a Welcome message from the Hotmail team remaining.
“As with all incidents like this, we will fully investigate the cause and will take steps to prevent this from happening again. We’re very sorry for the inconvenience this may have caused to you, our customers and partners,” the company said in a statement.
