Dear Customer,
We have identified and corrected an issue that could have resulted in unexpected charges with your Windows Azure free trial.
We identified an issue with our system behavior at the end of your Windows Azure free trial that inadvertently migrated your subscription to our Pay-As-You-Go offer. If you have any running Windows Azure services, your subscription may have generated charges. Because this may have not been your intent, you will not be billed for this usage for the current billing month on this Pay-As-You-Go subscription, subject to a $400 limit.
If you no longer desire to use this Windows Azure subscription and desire to avoid any future charges, please sign in to the Account portal and cancel the subscription noted at the bottom of this message.
We apologize for any inconvenience. Please contact Windows Azure Support if you have any questions.
Thank you,
Windows Azure Team
