Identified
We are now restoring the affected collaborations that were inadvertently removed due to this issue.

Affected collaborations will not be restored in any particular order. The remediation is a rolling process and as we restore the collaborations, users will again be able to access content in Box. Only collaborations and users impacted by this issue will be restored.

It will take some time before all collaborations are restored and we will continue to update here on our progress. 

As we restore the collaborations, please note the following behavior: 
- Box Admins will see "Auto accepted collaboration invite" events for restored user collaborations and "Collaborated group" events for restored group collaborations. These events will be logged by a "Box Support" user.
- Box Drive users will need to reapply the Make Available Offline option for affected content once access is restored. For more information, please see https://community.box.com/t5/Getting-Started-with-Box-Drive/Making-Content-Available-Offline/ta-p/58822.
- Box Sync users will need to mark folders for sync on Box.com again once access is restored. For more information, please see https://community.box.com/t5/Using-Box-Sync/Marking-Content-for-Box-Sync/ta-p/20360
- Box Mobile application users will need to reapply the Make Available Offline option to any affected content once access is restored. For more information, please see https://community.box.com/t5/Using-Box-for-iOS/Saving-Files-for-Offline-Access-in-Box-for-iOS/ta-p/251 for iOS and https://community.box.com/t5/Using-Box-for-Android/Managing-Content-with-Box-for-Android/ta-p/20133 for Android. 

The next update will be provided here by 5:30 PM Pacific or earlier if there is any significant change in the status.

Investigating
We are currently investigating reports of an issue that resulted in some users being inadvertently removed as collaborators from folders on Box. The affected users will no longer have collaboration access to the folders on Box including through Box Sync or Box Drive. While no content on Box has been deleted, users may report "missing" content due to losing access to the folder. Our engineering team has taken immediate action to prevent additional impact and are currently investigating all possible remediations.

Meanwhile, Business and Enterprise Box Admins can identify affected collaborators by running a User Activity Report* for Removed Collaborator actions from March 8, 2019 to March 10, 2019. Collaborators removed by "Box Backend Service" (noted in the Details column of the report) are affected by this issue. Please ask folder owners to re-add affected collaborators if immediate access to the content is needed.

The next update will be provided here by 11:00 PM Pacific or sooner if there is any significant change in the status.
