Microsoft has confirmed today that users of T-Mobile’s Sidekick communicator will soon have their data once again.

In a press release today, Microsoft revealed that the company has been able to recover “most, if not all, customer data” lost in Saturday’s outage.

We are pleased to report that we have recovered most, if not all, customer data for those Sidekick customers whose data was affected by the recent outage. We plan to begin restoring users’ personal data as soon as possible, starting with personal contacts, after we have validated the data and our restoration plan. We will then continue to work around the clock to restore data to all affected users, including calendar, notes, tasks, photographs and high scores, as quickly as possible.

Microsoft says that the loss of data was due to an architectural failure which compromised storage in both active and backup data.

The company is working with T-Mobile to complete the recovery process. Microsoft’s next official status update will come by Saturday, but users are invited to stay up to date on Twitter in the mean time.
