Some features of Microsoft Exchange Server accounts depend on the version of Exchange that your account connects to. An example is the Outlook Anywhere feature, which requires Exchange Server 2003 or later.
To determine the version of Exchange Server that you are connecting to, do the following:
- With 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.
- Under the column heading Version, note the number.
- Compare the number with those in the table below.
