[Medium] Issues with Box Relay

Final update

We recently addressed issues affecting Box Relay. We would like to take the opportunity to further explain these issues and the steps we have taken to keep them from happening in the future. Between 1:10 AM and 11:33 PM PT on July 14, 2026, some users may have experienced difficulties while working in Box. During this time, some users may have experienced degradation of Box Relay workflows that include a task outcome. The issue occurred as a result of a recent code change intended to improve how task assignments are handled in workflows. We were able to resolve the issue by reverting that change and restoring the previous behavior. In addition, we are improving our automated testing, monitoring, and deployment safeguards to prevent similar issues from occurring in the future.  ‌ **Analysis** A Box Relay workflow can include a task outcome, which assigns a task to one or more people. As part of that outcome, the workflow also attempts to give each assignee access to the relevant file. A recent change caused the entire task outcome to fail whenever that access-granting operation was rejected. Such a rejection is an expected condition in some configurations \(_e.g._, when the person

A recent change caused the entire task outcome to fail whenever that access-granting operation was rejected. Such a rejection is an expected condition in some configurations \(_e.g._, when the person who owns the workflow does not have sufficient permission to share the file, or when sharing restrictions are in place\) and it can occur even when the assignee already has access to the file. Previously these rejections were tolerated and the task was still created. After the change, they caused th
