Hi @Kumar, P. ab
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?
User has M365 E5 license and till now one user has reported this issue. When we try to open the attachment in the email then we receive the error. It works fine the OWA.
Hi @Kumar, P. ab
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?
No progress till now, the user is still facing same issue
Hi @Kumar, P. ab
Thanks for your reply!
If the problem only occurs in the Outlook desktop client, try creating a new profile to check if that helps.
Hi @Kumar, P. ab
Are there any differences in creating a new profile?
If you are not the scenario, we will do other troubleshooting.

We have the same issue with Excel and Powerpoint files. Both worked a few days ago. 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
after talking with the affected users, the problem is only for the Outlook New app.
after talking with some affected users, the problem is only with Outlook New. With the "normal" Outlook 365 there is no problem.
