Which Exchange version am I using?

I've read about several features I liked but they depend on the version of Exchange I am connecting to.

Aside from contacting my mail admin, how can I found out which version of Exchange I'm running against?

Exchange buttonThere is an option to check your connection status which also displays the Exchange version number.

  1. Start Outlook and connect to the Exchange server if this isn’t done automatically already.
  2. Hold CTRL while clicking on the Outlook icon in the Notification Area
    (located in the right bottom area near the time; expand the Notification Area first if the Outlook icon does not show).
  3. From the context menu that pops-up choose: Connection Status…

    Hold CTRL when clicking on the Outlook icon and choose Connection Status...

  4. Scroll the horizontal scrollbar to the right to see the last column.
    (if the dialog is empty, then you are not connected to Exchange)
  5. Here you’ll see a version number. Use the table below to determine which named version of Exchange it corresponds with.
    Your version number could be between 2 named versions. In that case, your named version corresponds with the lower version but with some additional update installed.
