Do you know how I can recover the files that suddenly disappeared from my OneDrive after my account was reactivated?

Hello @Davide Galuppi,  

Good day! Thank you for posting your valuable question on Microsoft Q&A forum.   

Thank you for reaching out, and I’m truly sorry to hear about the issue you're facing. Since your OneDrive account was recently reactivated, and your personal folders are missing, here are the steps I recommend: 

Check the OneDrive Recycle Bin 

Sometimes, files are moved to the Recycle Bin during account deactivation: 

• Go to OneDrive Web and sign in with your account. 
• On the left pane, click Recycle bin. 
• Look for your missing folders or files. If found, select them and click Restore. 

Files in the Recycle Bin are typically retained for 93 days unless permanently deleted. 

If the files are not in your Recycle Bin, check the Second-Stage Recycle Bin on your OneDrive: 

• In your Recycle Bin. 
• Scroll to the bottom of the page and click on Second-step Recycle Bin. 
• Select the items you want to restore. 
• Click Restore. 

The second-stage recycle bin may appear like this in your OneDrive: 

If you cannot find any files in your Recycle Bin, you may want to Restore your OneDrive: 

• Go to OneDrive Web and sign in with your account. 
• Select the gear icon (Settings) > Reset your OneDrive. 
• Under Select a date, choose Yesterday or any date you want. 
• Scroll down to see the changes on OneDrive and see if there is the version you want to restore > if so, click Restore. 

If after trying all the steps above, you still can't find the version: Contact Microsoft Support immediately and ask them to restore for you. Note that Microsoft support teams can only restore your entire site's data within 14 days for business accounts. 

For business support: 

1. Find your Microsoft 365 admin: If you don't know who the global admin is in your organization, you can find guidance here: How can I find my Microsoft 365 admin? - Microsoft Support 
2. Submit a service request: The Global Administrator should create a support request with Microsoft to receive advanced technical assistance. For detailed instructions, see: Get support - Microsoft 365 admin | Microsoft Learn
