How to fix error occurred while opening the file on outlook (new)

Answer 1

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!
