Some features of Microsoft Exchange accounts depend on the version of Exchange that your account connects to. An example is the Outlook Anywhere feature, which requires Microsoft Exchange Server 2003 or later.
To determine the version of Exchange that your account connects to, do the following:
With Microsoft Outlook running, press and hold CTRL while you right-click the Outlook icon in the notification area, at the far right of the taskbar.
Click Connection Status.
Move the horizontal slider all the way to the right.
Note: Under the Version column heading, note the number that appears.
Compare the number with those in the table below.
Note: Microsoft Office Outlook 2007 can be used with Microsoft Exchange Server 2013, Exchange Server 2010, Exchange Server 2007, Exchange Server 2003, or Exchange Server 2000.
