Hi @TANSINEE KAMCHAROEN ,

Welcome to our forum!

Does this issue occur when you open all attachments or the specific attachment?

In order to further confirm if the issue is related to New Outlook desktop client, please log in to you web mail and try to open the same attachment to check if the issue persists.

Based on my research, i found a similar mentioned that it's useful to change the below setting:

I also had the problem and digged in a bit deeper using sysinternals Process Monitor to see what exactly fails, when the system tries to download the file in the temporary outlook folder. There I figured out that my problem was a somehow missing Attachments folder! Please press WIN-R and type %userprofile%\appdata\local\microsoft\olk and press Enter. Then an explorer windows opens. Check if you can see an Attachments folder. If not create one and problem might be solved for you.

It's suggested that you could try it. More information: Why can't I open attachments in the new version of Outlook?

Hope to help you!

-Open all attachment on outlook(new)

Or notebook has both outlook(classic) and outlook(new), so it has a problem.

Hi,

Thanks for your help.

I have the exact same problem on two differents computers/accounts.

This issue occur when I open the file (excel/pdf/word...), but I can "save as", "preview" and "open in browser".

So I tried your suggestion, but I already have an "Attachments" folder, and even if I create a new one, the issue remains unsolved.

Best regards

@Emilien and @TANSINEE KAMCHAROEN, Same issue here. The attachements folder doesn't resolve the problem. According to this reddit article many users are experiencing the same issue with WebView2 v132.0.2957.115 version of New Outlook.

Thank you for your reply, but your information is out-of-date, Christy. That was back in September 2024. This is a new issue that started yesterday (22/01/2025).

I am also quite interested in any reply from Microsoft tech team.
Kind regards.

Hi @TANSINEE KAMCHAROEN ,

Thanks for your reply!

I found that the user mentioned the issue disappeared in this thread, it's suggested that you could upgrade your Outlook to the latest version to check if there're any differences.
