Outlook Web Access (OWA) allows any client with a compatible browser to access Exchange Server folders.

The “premium” version of OWA in Exchange 2003 looks and acts much like the Outlook 2003 desktop client, although it does not offer support for the Journal folder. The “basic” version looks more like previous versions. You may want to try both and see which is faster for the conditions your users are likely to encounter.

For Exchange 2000, you create applications using web forms. No conversion tool is available to turn Outlook forms into Exchange 2000 OWA forms. For resources and tools, see Microsoft Exchange Server Development Technologies. With Outlook 2002 and Exchange 2000, you can connect using OWA and Outlook 2002’s support for HTTP mail servers (at least those that use WebDAV). The correct URL would be .

There are issues using OWA on Vista because the dhtml text editor control used by OWA is not supported in Vista. The Exchange administrator should have installed the security patch for this on the Exchange server months ago, but many have not. The patch will fix this and a similar issue that affects Windows XP users who’ve installed the security patch described in MS06-013. The hotfix installs a new editor for Internet Explorer which uses an iframe instead of an ActiveX control.

If you are an end-user, contact your administrator. If you are an administrator, see the following links for more information and the hotfix.
