Can't customize ribbon in Outlook 2013

I want to remove one of the ribbon items on the main ribbon.  In particular, I want to remove the reply to all item.  It's just too dangerous.

When I go to the customize ribbon dialog the Reply to all is grayed out (as are all the peer items on reply).

How can I fix this so I can customize this ribbon?

it seems that it is not possible to simply remove the "Reply All" button from the default ribbon. But as a simple workaround you can easily create a new Ribbon Group that contains all the buttons except the "Reply All" button and completely remove the default "Respond" Ribbon.
Here is a short instruction on how to customize the ribbon:

1. Click File tab. Click Options. Click Customize Ribbon.
2. Choose the “Respond” Group in the right frame and click Remove.
3. Click New Group. Rename it as “Respond (Custom)”.
4. Select “Main Tabs” from “Choose commands from: ” on the top of left frame.
5. Expand “Home (Mail)” and “Respond” in left frame.
6. Select the “Respond (Custom)” in right frame.
7. Select and Add the commands “Post reply”, ”Reply”, ”Forward” , “Meeting” , ”IM” , ”More” from left frame to “Respond (Custom)” one by one.
8. Click OK.

Note: If you fail to set it, you can reset to default by clicking the button Reset (below the right frame) and choose Reset only selected Ribbon tab.

Pretty sad answer from MS I must say, but I guess I'm not surprised.  They kind of do everything half-assed.
