[Major] Issue Modifying Powerpoint Files with MS Office Online
Postmortem
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 May 14, 2025 at 9:32 PM PDT and May 15, 2025 at 04:04 AM PDT, some users may have experienced difficulties while working in Box. During this time, some users were encountering an error when attempting to open PowerPoint files via Box for Office Online. The issue occurred as a result of a recent Microsoft Office update. We were able to resolve the issue by working closely with Microsoft to diagnose and remediate the issue and restore service. In addition, we are working to enhance monitoring and alerting, and also improve escalation channels with Microsoft to decrease any possible downtimes caused by such issues and 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
