In OWA, what is the difference
between "Public or shared computer" and "Private computer"?
OWA 2007 has improved security for the logon page, which is
especially useful if you share a computer or access your email
from a public computer in a lab.
Your OWA session automatically logs you off after a certain
amount of time.
BE AWARE OF THE INACTIVITY TIMEOUT!
When you logon, you specify what
kind of computer you are using.
Using Internet Explorer, If you select "Private Computer", your
session will timeout after 8 hours. If you select "Public or
shared computer" your session will be closed after 15 minutes.
After your session closes, even if you leave your browser open
and someone tries to use it, they won't be able to access your

or another private setting, it's recommended you use the Private
If you type a lengthy email reply that takes longer than 15
minutes, with no other interaction with OWA, and you've selected
the Public option, your session will time out before you have a
chance to send the message. Either type the reply in a Word
processor and copy-and-paste it into OWA when you are ready, or
select the Private option on login. If you select the Private
option from a public computer, you must make sure to close the
browser or log off of the computer when you are finished or
others could access your mail.
NOTE: When you are finished using Outlook Web Access, click the Log Off button
on the toolbar. Logging off helps prevent someone else from using the computer
to access your mailbox. This is especially important if you are using OWA at a
public computer, such as in a library or at a conference.
Outlook Web App (OWA) provides two distinctly different interfaces, Premium
or Light, depending on the version number of the browser you use to access it.

The Premium interface comes closest to replicating the actual Microsoft
Office Outlook experience, with some right-click functionality and access to the
full feature set.
Requirements for the Premium interface
You receive the Premium interface when you are using Internet Explorer 7 and
above, FireFox 3 and above, Safari 3 on a Mac, and Google Chrome 5 and above.

Requirements for the Light interface
You receive the Light interface when you are not using one of the browsers or
browser versions listed in the premium interface section above, or you have
enabled the "Blind and low vision experience" option in OWA.
