Notice and disclaimer: Box is providing this preliminary information subject to further review and analysis. To the best of our knowledge, this is the current state and we may update as more information is confirmed.

Between November 5, 2024 at 12:00 AM PDT and November 7, 2024 at 10:00 PM PDT, some users may have experienced difficulties while working in Box. During this time, some users encountered an error when attempting to open PowerPoint files with Box For Office Online. The issue occurred as a result of a recent Microsoft Office update that was being gradually rolled out to users by Microsoft. We were able to resolve the issue by working closely with Microsoft to identify the cause of the issue; once Microsoft’s engineering team reverted the update, our service was restored. In addition, we are working to enhance monitoring and escalation channels with Microsoft to prevent similar issues from occurring in the future. 

‌

We are conducting a full engineering postmortem and our overview is subject to change with further analysis and findings. In the event our continuing investigation yields further substantive findings, we may publish additional analysis after the conclusion of the full engineering postmortem.

We are continuously working to improve Box and want to make sure we are delivering the best product and user experience we can. We hope we have provided some clarity here and we would be happy to answer any questions you may still have regarding this matter. 

Sincerely,

The Box Team
