我试图将我的 OneDrive 学校账户恢复到之前某个时间点的状态，但那些意外删除的文件仍未找回。

Hi LI, Ying

Thank you for sharing these updates and for your patience throughout this process. I understand how critical these files are to you.

To clarify, retention policies and the Preservation Hold Library are not included by default. Upgrading now will not recover previously deleted files because retention policies only protect content that was under policy before deletion.

The restore feature lists historical folder structures, but if the actual files were permanently deleted (and not retained by a compliance policy), the restore process cannot bring back their contents. Empty folders after restoring confirm that the underlying files are no longer available in the standard recovery path.

If the files are not in either location or no retention policy applies, unfortunately, recovery is not possible.

As mentioned, Microsoft Support or a forum moderator does not provide direct data recovery or remote access for deleted content. This is due to strict privacy and compliance requirements. Please understand that Microsoft cannot override retention limits or access user data beyond defined policies.

To avoid similar situations:

• Regularly download critical files to local storage or maintain a secondary backup.
• Consider enabling OneDrive sync client for offline copies.

Dear Flora-T,

Many thanks!

I searched some social media blogs, and noticed someone mentioned a solution that works: let school's Microsoft 365 administrator to contact Microsoft company, to apply 'Time-In-Point Restore'. This blog is posted very recently (only 5 days before my accident), and his situation is even worse than mine because he also emptied the second-stage recycle bin. I have contacted my school's IT colleagues, but they replied this appraoch is something similar to 'Restore Your OneDrive' done by myself. Could you please kindly provide any details about this solution, so that I can let my shool's colleagues to have a try.

Hi LI, Ying

Thank you for sharing this information.

Based on my research, there is no separate Microsoft feature called “Time-In-Point Restore” for OneDrive. This term may be used in blogs to describe the official Restore your OneDrive feature.

However, to make sure, could you please share the exact blog details you found?

Dear Flora-T,

Thanks for helping.

Sorry for writing it incorrectly, it is 'Point-In-Time Restore' PITR'. The blog is from Chinese social media. The blogger (also a student account) emptied the second-stage recycle bin too, but his school helped contact Microsoft, and after sigining some consents, his files are finally recovered. Kindly please refer to the attachment.

Hi LI, Ying

As a last resort, I recommend asking your school’s IT team to contact Microsoft Developer Support through the Services Hub for further assistance. Please note that this option involves a paid support ticket, and access is subject to certain conditions. You can review the details here: Services Hub sign in FAQs | Microsoft Learn

It’s important to understand that data recovery is not guaranteed for all cases, even through this escalation process. Microsoft evaluates each request individually, and success depends on factors such as backup availability and compliance requirements.

Hi LI, Ying
May I know if you have checked my response?

If you found this discussion helpful and feel it addresses your concern, even partially, please consider accepting my initial answer. Doing so helps others in the community who may be facing similar issues find it more easily and brings visibility to this discussion.

I truly appreciate your time and contribution.

Dear Flora-T,

I have forwarded your last suggestion to my school's IT team. According to their reply, seems they already initiate the communication with Microsoft.

I have another concern: Although I have mentioned Point-in-time restore (PITR) service on 24 Oct, I did not get feedback regarding this point until 28 Oct. Here I am not intending to blame on this, instead I am worry about the time needed for file recovery, because the blogger told me the recovery should be finished within 14 days after deletion. Since my deletion took place on 18 Oct, 14 days' limit is approaching the corner. In this regard, could I kindly seek your help to accelerate this process with your Microsoft colleagues if they have received the request from my school?

Thank you so much for help all the way. I have accepted the initial answer.Weixin Image_20251030143201_453_114.png

Hi LI, Ying

Thank you for sharing this update and for explaining your concern about timing.

At this stage, since your school’s IT team has already initiated communication with Microsoft, the case is now handled directly between them and Microsoft engineers. Unfortunately, as a forum moderator, I do not have access to internal escalation channels or the ability to accelerate the process. The timeline depends on factors such as backup availability, consent documentation, and Microsoft’s internal review procedures.

The best approach is to stay in close contact with your school’s IT team. They will receive confirmation from Microsoft and guide you through any required steps. If you haven’t already, you can ask them to confirm that all necessary forms and details have been submitted promptly to avoid delays.

I truly hope the process completes successfully for you.

Dear Flora-T,

Still, thanks for your help and patience during the long procedure!

My school's IT team has already submitted a ticket to Microsoft, and their response was as follows: “Usually we can restore OneDrive site to past 10 days. It is October 31, 2025 today. We can restore the OneDrive site to any time between October 21 and yesterday. "

Since my deletion disaster took place on 18 Oct, the reply is: “Microsoft said that they can try to restore the entire OneDrive site to 18 Oct 1:00 AM UTC+8. But they are not sure if it works."

I have been trying to figure out solutions since the disaster happened. However, my communication here and also with my school takes a long time and causes delays, making it exceeding 10 days' "usual" limit. I hope Microsoft team could try their best to help on this disaster........This is my last hope.

Thank you so much for the help!!!!! I will update the final progress.

Hi LI, Ying

Thanks for your prompt update, your feedback truly means a lot. I understand you’ve done everything possible to maximize the chances of recovery, and I sincerely hope this final attempt works out for you.

Dear Flora-T,

Thanks so much! I would like to update here that after the efforts of my school and Microsoft, all of my missing files have been recovered successfully. Thank you for taking care of this issue and the help all along this process.
