I often use Right Click -> Send To -> Mail Recipient on a file to send it as an mail attachment. But the problem with this approach is that the message opens in Text mode. Means you cannot format text/insert table/graphics etc by default. [You need to select HTML/Rich Text from Option ribbon tab].
So, here is the solution:
Find the SendTo folder
For Windows 7 it is C:\Users\username\AppData\Roaming\Microsoft\Windows\SendTo
For Windows XP, just type SendTo in Run
Create a Shortcut there with reference to Outlook.exe
(Which probably would be under “C:\Program Files\Microsoft Office\OFFICE12\OUTLOOK.EXE”)
Append /c ipm.note /a in the shortcut, so that the complete shortcut will look like:
“C:\Program Files\Microsoft Office\OFFICE12\OUTLOOK.EXE” /c ipm.note /a
Name the shortcut whatever you like.
And done! ENJOY!!
