This question came from our site for professional and enthusiast programmers.

Right click on one of the attachments, and see if there's an "open with" option. – Gilbert Le Blanc Apr 7 '11 at 18:48
or uninstall Excel Viewer :) never heard of it before. it might also help if you have normal Excel already open. helps me sometimes so that I dont have to wait for 10 addins to load – Bek Raupov Apr 8 '11 at 8:31
When you open an Excel file from Windows Explorer (e.g. by double clikcing on it), what does it open with? Excel or Excel viewer? – paulmorriss Apr 8 '11 at 13:33

As paulmorriss pointed out, you should tell us what happens when you open a file from the Windows Explorer.
Yet, I've never seen an option where Outlook would open files with another program than the Windows Explorer.

Here is what you (or whoever has the same problem) can try:

  • save your file to your Desktop
  • hold SHIFT while right-clicking the file
  • from the Open With list, select Choose Program and select Excel
  • make sure that you also check the box Use this program as the default

The next time you open such a file type, it should open directly with that program (even from Outlook).
If you still have this issue, tell us your version of Windows and eventually Excel.

Assigning File Extensions to Programs

  • Click on your Start Menu. In the search bar type "Default Programs" and hit enter.
  • The second option should be "Associate a file type or protocol with a program".

Microsoft Excel's most common file extensions are .xls, .xlsx, .xlm, and .xlsm.

  • Scroll down toward the bottom where you will find the above mentioned extensions.
  • Select the extension you wish to assign to Excel.
  • In the upper right area of the window select "Change program".
  • Select Microsoft Excel from the list of programs.
  • Hit OK

If Microsoft Excel is not in the list of programs to choose from, select "Browse" and rows to the install folder of Microsoft Excel and select the program from there.

For example: C:\Program Files (x86)\Microsoft Office\Office14

This Method will allow you to assign any file type to the Application/Program of your choice.
