Receiving unsolicited OneDrive File/Folder shares, how do I stop it?

Phillip Confused 65

Recently strangers (AI driven bots) have started sending me emails sharing links to their Microsoft Onedrives!

How do I stop this from happening?

Are there any security concerns (Viruses/Malware)?

Am I liable if they attempt to share any illegal content?

I receive the Email into my junk folder which I can't stop and then I get a Onedrive notification of the file/folder share. What can I do?

Thank you very much for any advice.

Regards

Phil

Hi, How can I turn off receiving shared files in OneDrive? I don't want to risk it.

This is a significant security risk and Microsoft needs to address this pretty urgently. Allowing people to share files with you, which you can ONLY hide is a serious flaw. ITs fine someone wants to try and share something with me but I need to have the ability to accept or reject it not just hide the file. This is allowing an attacker to flood people's onedrive with unsolicited and malicious files and the recipient has no control (other than to hide)...

Hello Phillip Confused,

Thank you for posting your question in the Microsoft Q&A forum!

I understand that you have confusion when receiving OneDrive share notifications. That's very understandable and believe me you're not alone. I am here to help you out.

As your description, someone share OneDrive files with your Microsoft account email and Microsoft sends notifications by default. With this case, Are there security concerns?

Yes, potential risks exist:

The shared links could lead to malicious files (viruses, ransomware, phishing).

Clicking the link or downloading files could compromise your device.

Best practice:

Do NOT click any links from unknown senders.

Ignore or delete the notifications.

Keep your antivirus and Microsoft Defender up to date.

Are you liable if they share illegal content?

No, you are not liable just for receiving a share.

Liability only arises if you download, store, or redistribute illegal content.

Simply ignoring or deleting the share keeps you safe.

Therefore, I have these suggestions for you:

Block the sender’s email

In Outlook.com or Outlook app, add the sender to your Blocked Senders list.

This will stop future email notifications from that address.

Disable OneDrive share notifications

Go to OneDrive Settings → Notifications: Uncheck “Someone shares files with me”.

This stops the in-app pop-up notifications (but not the email unless blocked).

Report the share

In the OneDrive web interface:

Open Shared → Files shared with you.

Select the suspicious share → Remove.

Optionally click Report abuse.

Enable stricter spam filtering

In Microsoft 365 Security & Compliance Center (if you have a paid plan): Add rules to quarantine external sharing notifications.

I hope this will help with your situation. Please feel free to reach back if you have further update or more questions.

And where do you find "remove" function - there is only "hide from shared" which clearly is not a removal?

I received a OneDrive notification that a file was shared with me. I tried deleting the files, but there is no option to do so. I need help removing these files and preventing future harassment — for example, how can I restrict who can send shared files to me?

Hello Phillip Confused,

Thank you for your respond.

As your concerns, unfortunately, you can’t delete files that others share with you in OneDrive because you don’t own them, but you can remove access and block future sharing. I suggest you:

1. Remove the shared file from your OneDrive view

Go to OneDrive on the web.

In the Shared section (left panel), find the file or folder.

Select it, then click Remove from shared list (or stop sharing if you own it).

This removes it from your view, but the owner still has the file.

2. Block the sender from sharing with you

Unfortunately, OneDrive doesn’t have a direct “block sharing” feature, but you can:

Block the person’s Microsoft account:

Go to People & Contacts.

Find the person and choose Block.

Report abuse if the sharing is harassing Use Microsoft Report Abuse and select OneDrive.

If you have any updates or further questions, feel free to tag me in your reply so I can assist you more directly. I'll be happy to.

Best Regards,

Hello together, I have an similar issue. The malicious shared folders / files show up directly in my one drive and I receive a notification on my iPhone. It‘s already the 7th folder in < 24h… I don’t want to have to delete every single folder/ file manually. Is there no possibility in settings to only receive shared files/ folders from contacts ? And if no, why not?

This is a significant security flaw with Microsoft. As a user of this platform I should not have to suffer receiving unsolicited onedrive shares, hiding it is not sufficient, its unreasonable to have to keep blocking users, it creates a risk because it floods your shared files area which can mistaking lead to users opening them and being exploited.

This is ridiculous! Microsoft is exposing users to malicious attacks. They can release instructions for blocking/reporting/deleting, etc., but the fact remains. Across millions of users, privacy and security breaches WILL occur in hundreds or thousands of users.

The only remedy here is to report and delete? block "notifications" but not block malicious attacks?! Please tell us you're doing something about this...

Hello Andorus, MadPeanut, ToW, Joao Carlos Fernandes Serodio, A S,

Thank you for posting your question in the Microsoft Q&A forum!

I understand that you’re facing the same issue with receiving unwanted OneDrive folder-sharing notifications. I’m truly sorry for this inconvenience when getting spam shares without any way to block the sender must feel very frustrating. I completely understand how upsetting this can be, and I’m here to help.

1. Contact Microsoft Support for escalation

Since these unwanted shares happen every few hours, this is considered persistent harassment.

Please reach out to Microsoft Support through https://support.microsoft.com/contactus → Sign in → OneDrive → For Home Use → Chat or Request a Call.

You can explain: “I am receiving repeated unwanted OneDrive shares without email notifications and I have no option to block the sender. Please help escalate this issue.”

2. Submit feedback

Your feedback is very important to us, it helps our engineering team improve the product for all users. Visit here: Send feedback to Microsoft with the Feedback Hub app

Please understand for us that, we don’t have access to your personal account, your subscription, or your OneDrive data, so we’re not able to control who sends you shared files or stop those shares from your side. To help prevent similar issues in the future, it’s also a good idea to be careful when sharing your email address or personal information on external websites or services.

I truly hope this helps, and I’m always here if you need more assistance or have any updates.

Best regards,

I'm getting the same issue. Worse, although I can report several of these messages for spam, and within a few hours, the files are removed and blocked, there are several files which I can not report. It says: "Sorry, something went wrong. Please try again later." What setting do I need to change in order to report these files, which are clearly spam at best and potentially viruses or malware at worst?

I had about 20 and was able to report most of them, but not all. I figure by reporting, I'm increasing the likelihood that the account gets blocked, and thus perhaps reducing the impact for other people.

Thanks for any help here. It just started a few days ago.

How about Microsoft create a setting in OneDrive that allows users to only allow files from contacts?

I've had the same problem since yesterday. What's more, I'm receiving it on an alias that I created solely for the purpose of logging into my MS account, so it's doubly strange to me - it hasn't been used anywhere besides Outlook/Onedrive loggin(did microsoft leak my login????). On the other hand, since it's an alias for logging into my account, I haven't configured it as an email address at all so no spam email jst notifications and sus pdfs in shared onedrive.

I have the same issue. My OneDrive get Spammed by bots sharing content with me. It is a huge security flaw. I am a paying customer and recieve 50-100 Spam emails pr 24 hours. Now I have to delete hide SPAMfiles shared with me on top of reporting all that SPAM in Outlook. This is super annoying. It is clearly someone found a way to bypass all security in Microsoft. Just add the feature that only people in my contaclis are allowed to share with me and this issue would be managable.

If Microsoft is not fixing this issue and filtering better, I need to protect myself and move to a different provider that take better care of me.

If this is not fixed by January I will move to a different plattform and pay them for better security.
