This is annoying if you have certain keyboard shortcuts hardwired. For instance, in Outlook 2003 (and Word) one could access the “Paste Special” command (which gives a number of optional formats in which content can be pasted into a document, including unstyled text) with the keyboard shortcut alt+E, then S. Alt+E is an old Windows keyboard shortcut that allows accessing menus using their accelerator key, and for several Outlook releases, “Paste Special” has had S as its accelerator command.
Fast forward to Outlook 2007. The editing window uses the Ribbon, rather than menus, and so alt+E doesn’t do anything. However, alt+S does. So if you happen to hold down the alt key and type E S, thinking you’re going to paste something in the message, Outlook will merrily send it, minus whatever you were going to paste, instead.
Is there a solution? The only way around the issue that I’ve found requires writing a macro to invoke the functionality, assigning the macro to a custom toolbar button, and then mapping that button to a keyboard shortcut (say, alt+E). Convenient? No. Quick? No. In fact, there doesn’t seem to be a way to make it work consistently in Outlook at all.
Sigh. Hope we can get this fixed at some point.
