Question details

Users are experiencing issues where recipients are unable to open files attached directly from OneDrive via email, receiving a refresh error instead.

How to Fix OneDrive Email Attachments That Recipients Cannot Open

Product: Microsoft OneDrive and Outlook
Device & OS: not provided
Scenario: Sending files stored in OneDrive as email attachments through Outlook or Hotmail.
Observed behavior: Recipients receive a refresh error and cannot open the attached file. However, standard OneDrive sharing links and locally saved files attach and open correctly.

Before you start

Check the Microsoft Service Health dashboard to ensure there are no ongoing server outages or incidents affecting OneDrive, Outlook, or general attachment processing.

Solution 1Recommended

Save a Local Copy Before Attaching

Use this tested workaround to ensure recipients can access the files by bypassing the direct OneDrive attachment integration.

Since the direct attachment feature from OneDrive can sometimes fail due to sync or server issues, saving the file locally forces the email client to treat it as a standard static file.

Download the file

Open your OneDrive folder or the OneDrive web interface, locate the file you want to send, and download it to your computer's Desktop or Downloads folder.

Create a new email

Open your email client (Outlook, Hotmail, or preferred browser interface) and start composing a new message to your recipient.

Attach the local file

Click the attachment icon, browse to the location where you saved the local copy (e.g., your Desktop), select the file, and attach it to the email.

Reliable Workaround: This method guarantees the recipient receives a physical copy of the file that does not rely on Microsoft's cloud servers to open.

Solution 2

Share a OneDrive Link Instead of an Attachment

Sending a secure link avoids email attachment processing errors entirely and ensures the recipient accesses the correct file.

Solution 3

Disable Attachment Preview in Outlook

Adjusting Outlook's Trust Center settings can occasionally resolve rendering and opening errors for incoming and outgoing attachments.

Frequently Asked Questions

Why can recipients open my OneDrive links but not direct attachments?

When you attach directly from OneDrive, email clients sometimes fail to process the cloud integration properly, resulting in a refresh error or an unreadable file. Sending a standard sharing link bypasses the email client's internal attachment processing.

Will reinstalling or resetting OneDrive fix this email issue?

Usually, resetting or reinstalling OneDrive does not resolve this specific issue. The problem often lies within the backend communication between OneDrive and the email provider (like Hotmail or Outlook), which is why local saving or link sharing is the best workaround.

Could my antivirus software be blocking the email attachment?

Yes, overly strict antivirus or firewall settings can block cloud-linked email attachments from opening. You can try temporarily disabling your antivirus to see if the file opens, but be sure to re-enable your security software immediately afterward.
