I found how to make a global hotkey shortcut that opens a new email and I’ve found it quite useful.

  1. Create a new shortcut on the desktop.
  2. Point it to the outlook.exe file.
  3. In the Target field append /c ipm.note at the end.
  4. Select a key for the shortcut field. (I selected “m”, ctrl+alt will be automatically added.)

new_mail_shortcut

"C:\Program Files (x86)\Microsoft Office\Office16\OUTLOOK.EXE" /c ipm.note

Now I can press Ctrl+Alt+m anywhere and I get a new email window in Outlook.
