Nope. Microsoft should fix their documentation. OWA 2003 does NOT render Exchange 5.5 mailboxes. Different technology is used - Exchange 5.5 uses MAPI from OWA application to the mailstore. Becuause of the limitations, Microsoft chose to use alternate technology, HTTP to access the users' mailstores. Since 5.5 doesn't understand HTTP when asked about it (not the same way), an Exchange 200x FE server will not render a 5.5 mailstore.

However, this article seems to state it is backwards compatible. http://www.msexchange.org/tutorials/Migrating_Exchange_5_5_to_2003.html "Replacing your existing OWA Front-End Server will be very easy, because the new release will provide backward compatibility with Exchange Server 2000 and 5.5. The new look of Outlook Web Access will be provided to each user, if both - back and front-ends are on Exchange Server 2003." However, it seems somewhat contradictory. Anyone have this working? ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: al.mulnick@xxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist
