In my line of work, I frequently need to open many Excel and PDF files. Previously, I could simply double-click a file and it would open immediately; now, however, when I double-click, one of two things happens:
I get an error message prompting me to restart Outlook (which I’ve tried, but it doesn’t help).
The system attempts to download the file via OneDrive, but it never actually completes the process (and, in any case, I don’t want it to download via OneDrive).
My current workaround is to download these files locally before opening them, but that is time-consuming.
Is there a solution?

Thank you for providing the additional information.
Since you are using New Outlook for Windows with systems running Microsoft Edge version 156 and the behavior occurs with all attachment types, the symptoms align with the service-related behavior currently affecting some users when opening attachments directly from New Outlook.
You can check the details of this service issue in my previous answer.
At this time, the recommended approach is to continue using "Save As" to download the attachment locally before opening it.
Microsoft has developed and deployed a targeted fix to disable the underlying configuration responsible for this behavior. The change may take up to 12 hours to propagate across the service infrastructure. Once the update has been applied, please fully close and reopen New Outlook for the change to take effect.
If the issue persists after the propagation period has passed, please let me know and share any updated error messages so that further investigation can be performed.
Thank you for your patience.

Hello @Arreola, Rolando ,
I hope you're doing well and thank you for sharing the details.
Before jumping into any conclusion, could you please provide the following information:
This additional information would help determine whether there is any separate client-side factor contributing to the behavior.
Based on the behavior described, it appears that the attachment-opening experience in New Outlook for Windows may be affected by a recently identified service-related behavior associated with systems running Microsoft Edge version 156.
Impacted users may receive a message indicating that the file cannot be opened and that Outlook should be restarted. In some cases, the Open option for attachments may also become unavailable, which can result in files being downloaded instead of opening directly in the desktop application.
A service-side adjustment has already been deployed, and the change is currently being applied across the service infrastructure. Once the update has propagated, closing and reopening New Outlook should allow the updated configuration to take effect.
If you have Microsoft 365 administrator privileges, please sign in to the Microsoft 365 Admin Center using this link to view the details of this issue.
Alternatively, follow these steps:
As a temporary workaround, selecting "Save As" to download the attachment locally and then opening the file directly is expected to bypass the behavior.
I hope this information helps. If you need any further assistance, please feel free to leave a comment.
Kind regards.
