When downloading Office 2007 format files from a Connect site, they get downloaded as .zip files instead of, for example, .xlsx.

For example, the Windows 7 site, at this URL "https://connect.microsoft.com/windows7/Downloads/DownloadDetails.aspx?DownloadID=19322" offers the file WindowsServer2008R2RCandWindows7RCGroupPolicySettings.xlsx for download. When I click on the Download button/link, the file gets downloaded as WindowsServer2008R2RCandWindows7RCGroupPolicySettings.zip.

I too can't find the bug Yi mentioned below...

I also find this annoying. One cannot open an xlsx file that is attached to a Connect post.
Instead you have to save it and convert the zip extension back to the original, navigate to the folder containing the saved file and open it.
I would happily support the other thread but my search only found this one, and searching for 433629 produced no results.

This is an issue with Win7/IE8 combo that for some reason treats all 4-char office file formats (docs, xlsx, etc.) as .zip files.

We are going to close this one as duplicate of another customer filed bug: ID 433629. Please vote/comment on the other one.

Thanks you,

We have this exact same problem with our Outlook Web Access on our Exchange server. The attachment shows as .docx or .xlsx but after you download it the extension is .zip

Can you download a xlsx file from a Microsoft site? (For Example) http://www.microsoft.com/en-us/download/details.aspx?id=25250

In case you can download a xlsx file from MS (web site), check the MIME configuration on the server side.

Download the file as <filename>.ZIP. Rename the file to <filename>.xlsx or appropriate XML extension, and open it with associated program.
