On August 31, 2023, we began to communicate an upcoming update to our cloud storage infrastructure that would result in a change in how OneDrive photos and photo albums data is counted against your overall cloud storage quota.
This change was scheduled to start rolling out on October 16, 2023. Based on the feedback we received, we have adjusted our approach, we will no longer roll out this update.
We will maintain the current photo album experience, as it is today.
