I get this error message when trying to open any type of attachment from the desktop version of the new Outlook.

"Error occurred while opening the file. Please try again".

Hello,

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.

    Been dealing with this issue since January 20th. Tried other suggestions in this thread with either no or temporary effect. This reset worked for me. Thank you!

    I had a client with the same issue and I found a solution that worked for us.

    The Attachments folder was already there. I deleted it and re-added it, and no fix.

    I renamed the EBWebView, and no fix.

    What did work was reset the app in the Installed Apps settings.

    Right click Start Menu > Installed apps > Outlook (new) > Advanced options > Reset

    I then tried opening the Word attachment three times and it said to restart Outlook each time. I restarted each time. The fourth time, I double clicked the attachment and it opened in the Desktop app. The next time, the Open button from the preview window worked.

    Reset did the trick for my case.

    Thanks a lot :)
