How to Fix OneDrive Attachments Opening as Blank Files in Outlook
Question details
Files attached directly from OneDrive in Outlook open as completely blank documents for the email recipients.
- Product
- Microsoft Outlook and OneDrive
- Device & OS
- not provided
- Scenario
- Attaching documents (such as Word or PDF files) to an Outlook email directly from a connected OneDrive account.
- Observed behavior
- The recipient receives the email successfully, but upon opening the attachment, the document appears completely blank despite the original file containing data.
Verify that your original file on OneDrive is fully synced and not corrupted. Ensure that your Outlook desktop client and OneDrive application are updated to their latest versions.
Download and Attach the File Locally
Bypassing the direct OneDrive cloud link by saving a local copy of the file is the most reliable workaround for this attachment bug.
When Outlook struggles to fetch the complete file data directly from the OneDrive cloud service, it may attach an empty placeholder. Downloading the file to your local drive ensures the email client can access and encode the full document contents.
Open your OneDrive folder via File Explorer on your computer or log into the OneDrive web portal in your browser.
Right-click the document you wish to send and select 'Download', or copy and paste the file directly onto your local Desktop.
Open Outlook, compose a new email message, click 'Attach File', and choose 'Browse This PC'. Select the local copy you just saved from your Desktop.
Send the message as usual. Because the file was attached locally, the recipient will be able to view the contents without issue.
Report the Issue to Microsoft Support
Since this is a known bug with Microsoft's ecosystem, reporting your specific scenario helps escalate the need for a permanent software patch.

Frequently Asked Questions
Why do PDF and Word attachments from OneDrive arrive blank?
This is typically caused by a synchronization glitch between Outlook's attachment handler and the OneDrive cloud service. The email client finishes sending the message before the actual file data is fully downloaded from the cloud, resulting in a 0-byte or empty placeholder file.
Does this issue affect all email attachments?
No. It primarily affects files that are attached directly from a OneDrive cloud link within Outlook. Files that are stored locally on your computer's hard drive and attached normally do not experience this problem.
How can I check if my sent attachment is blank?
You can verify the attachment by going to your 'Sent Items' folder in Outlook, opening the email you just sent, and double-clicking the attached file. If it opens as blank for you in the Sent folder, it is blank for the recipient.
Can the recipient recover the data from the blank file?
Unfortunately, no. If the file was sent as a blank document due to this sync bug, it contains no actual data. The sender must use the local-save workaround and resend the file.
