Ewan is a tall chap who used to work in the SE team (which was the team I joined in Microsoft) many years ago.  He then went off and did some Exchange EMEA type roles and his skills were sorly missed.  Well, he is back "in the UK" (he never left, but his heart was elsewhere). And this posting is beginning to cause a bit of a stir.

My favourites are for quick keyboard things in Outlook:

• In Outlook, CTRL-2 switches to the Calendar, CTRL-3 to Contacts, and CTRL-1 back to Inbox. Handy if you're often flicking around to arrange a meeting with lots of people...
• Still in Outlook, when viewing the Calendar ALT-= switches to Month view, ALT- "-" (next to equals sign) switches to the week view, and ALT- number displays the number of days forward from the current date (eg ALT-9 will show 9 day view).

Have a look to see what else he can teach you :-)
