Dear Giovanna Meriade Farias
First and foremost, we would like to sincerely apologize for any inconvenience this issue may have caused. We truly appreciate your patience and understanding as we work toward resolving it.
Based on the information you’ve shared, it appears that the issue involves missing tasks in Microsoft Planner, which currently cannot be restored directly through the user interface. This may be related to how data is synchronized, stored, or processed within the Microsoft 365 system.
To address this effectively, we recommend contacting Microsoft’s technical support team. A support engineer will be able to initiate a remote session to investigate the issue, verify backend configurations, and use the necessary tools to attempt data recovery. If further analysis is required, they can escalate the case to a specialized team.
As forum moderators, we are limited in terms of access to system logs and backend tools due to privacy and security policies. Therefore, the most effective solution is to reach out directly to Microsoft Support.
