OWA 5.5 will access mailboxes on E2K servers just fine[1]. E2K OWA will not access MSX 5.5 mailboxes.
You will want to make sure your OWA 5.5 server is at SP4. You will also want to install Q313576 and Q321006[2] or else the "ASP0115 error" fairy will come and visit your OWA 5.5 server often... At some point before you retire your last MSX5.5 server, edit the registry on your OWA 5.5 server and change the key HKLM\system\currentcontrolset\services\msexchangeweb\parameters\server to one of your E2K servers. I've also found that OWA 5.5 seems a bit more stable on Windows 2000. 1. Outside of some minor bugs such as free-busy isn't updated on the server until you log out of OWA. 2. These hotfixes require at least IE5 (IE5.5SP2 or better highly recommended) be installed on the OWA server. If you don't, your messages will display blank bodies. -----Original Message----- From: Miller, Robert [mailto:[EMAIL PROTECTED]] Sent: Monday, December 16, 2002 1:53 PM To: Exchange Discussions Subject: OWA All, Quick question: We are in the process of upgrading from NT4.0 to AD, and from Exchange5.5 to Exchange2K. We currently have 3 OWA servers (5.5), and would like to keep the same setup in Exchange2K. For a period of time during the migration we will have some users on 5.5 and some on 2K. Do I need to get 2K OWA servers up on line prior to any mailbox migrations, or can a 5.5 server re-direct to a 2K mailbox? Or can I bring up the 2K OWA servers initially and redirect to a 5.5 mailbox? The 2K servers will joining the 5.5 Organization.
