OWA (Outlook Web Access) is the online companion to Microsoft Office Outlook. There are two versions of OWA available: OWA Premium and OWA Light. What is the difference between OWA Premium and OWA Light? OWA Premium employs a fully-featured interface that is similar to the Outlook client but is only available to those using Internet Explorer 6 or later as their browser. OWA Light also has a rich set of features for a ‘light’ application and is accessible with via Safari, Firefox, Opera and older Internet Explorer browsers. OWA Light is the preferred application for those using a dial-up connection, anyone working in a lock-down browser mode (e.g. kiosk), or for blind and low vision clients who need accessibility support. For more information about OWA Light, read the product designer’s blog about OWA Light. Both OWA Premium and OWA Light will provide access to mail and calendars. Are their features in Outlook that are not available in either OWA Premium or OWA Light? Yes. See the Featu
OWA or Outlook Web Access, is a webmail service of Microsoft Exchange Server 5.0 and later, originally called Exchange Web Connect (EWC). OWA is used to access e-mail, calendars, contacts, tasks and other mailbox contents while on the go. Microsoft provides Outlook Web Access as part of Exchange Server to allow users to connect remotely via Web browsers. Most of the functionality in Microsoft Outlook is also available in this web “look-alike”. OWA can be used from your classrooms, homes and any other location that provides connectivity to the Web. The OWA interface available in Exchange 2000 and Exchange 2003 is available in two flavors. The “Premium” UI is rendered for Internet Explorer 5 and later. The “Basic” UI is rendered for other browsers. All Administrator and Teacher PC’s have at least IE 6.0 or better. So when you logon to your email account, leave the Client and Security radio buttons set as they are.
OWA is a feature in Exchange 5.5 and 2000 that allows users to access their email via a web browser instead of a mail client. Essentially, OWA makes an Exchange server also function as a web site that lets authorized users read or send mail, manage their calendar, or perform other mail functions via the Internet. What’s wrong with OWA? When OWA processes a request from a user to access a particular mail folder, it doesn’t verify first that the folder actually exists. By levying a request involving an extremely complex folder structure – for instance, a folder nested ten thousand folders deep in a tree – it would be possible to make the server spend an inordinate amount of time processing that request. Would the folder have to actually exist? No, the requested item does not have to be valid. Any very deeply nested request can exploit this vulnerability. What would this vulnerability allow the attacker to do? By repeatedly sending requests that involve deeply nested folders, the attacker
