Welcome to our forum!
For a better study, please provide more details about this case:
What is your account type?
Do other users in the organization have the same problem?
Did you double-click to open the message or preview the file with this issue?

We are using Outlook 365 and did not tried to open the files from a pre view. Double click the email and double click on the attachment. With OWA it is working. A few other users are also have this problem. But not all.
Thank you for your help

Thanks for your reply!
We've seen feedback from multiple users on this issue, possibly a temporary backend bug, are you making any progress now?

Thanks for your reply!
If the problem only occurs in the Outlook desktop client, try creating a new profile to check if that helps.

Are there any differences in creating a new profile?
If you are not the scenario, we will do other troubleshooting.
