I am unable to download any attached files from my outlook.com account. I have 2 accounts one account is working fine and I have no problem downloading any attachments. The other account gives me an error message "Something went wrong with the request. Try again in a little while". I have been receiving the same message for the last several days. The problem persists on multiple computers. I can see all previews of the documents fine but receive the error every time I try to download any attachment. Clearing cache and forwarding the email to myself made no difference. My storage is showing 10gb used out of 100gb available. Your help is great appreciated

There is now a Microsoft Service Advisory for this issue.

Users may be unable to download or open email attachments in Outlook on the web
https://admin.cloud.microsoft/?#/servicehealth/:/alerts/EX1275040

Issue ID: EX1275040. Affected services: Exchange Online. Status: Service degradation. Issue type: Advisory. Start time: Apr 9, 2026, 6:48 AM CDT. Scope of impact: Some users attempting to download or open email attachments in Outlook on the web are impacted. This information may be updated as our investigation continues.

Current status Apr 14, 2026, 3:09 PM CDT

Our HAR trace analysis has focused our investigation to a token failure that we believe could be preventing the opening of email attachments for users in Outlook on the web. We're further analyzing the isolated failure to confirm our findings and so our next troubleshooting steps for remediating the impact can be determined.

[Not Official - Based on the reports I have seen, if an account is hoarked then you will see the same problem using both Outlook Web and New Outlook for Windows]

If you do not have direct access to Microsoft Service Advisories, open the thread below and click the [Follow Question] button. I will be updating this thread as updates from Microsoft are released.

    Hi Mike,

    The issue seems to be related to PDF files.

    This is a known issue it seems as we have gotten several reports. I hope you tried a private Window as well.
