Suddenly cannot download any attachments from outlook.com

Question

Suddenly cannot download any attachments from outlook.com

MikeM 20

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.

The Service Event that this thread is all about was closed/fixed some time ago. If you are now seeing the problem on only one account, then I would suggest that you:

1 -- Start a new thread using the "Ask a question" button at the top of this page to create a new Question and include the details for your specific problem. (You can put the link for this page in your new Question for reference)

2 -- Bring in Microsoft Support so they can examine your Account on the Microsoft server.

Logon to https://outlook.live.com/ with the Account that is having the problem.

From the main menu: Help -> ? Help

{This should open the Help side panel}

Search Help -> {Your problem} and press Enter

Still need help? [Yes]

If you get "We're here to help": Tell us your problem -> {Your problem, again} [Get Help]

[Sign In] {Use any Outlook/Microsoft account}

Thanks, Mike. Does the issue persist with an Inprivate Window as well?

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.

My issue is not specific to PDFs. I am also having the same problem with MS office files but only with the one account. Thank you for the information on how to submit a feedback, I have already reported the problem.
