Exchange 2010 autodiscover redirect question

not sure if this is possible, but we have Exchange 2010 deloyed in a co-existence mode with our exchange 2003 Org. [same domain / forest]
Does anyone know of a way, that if a user that still has a mailbox on Exchange 2003, but uses a later client like Outlook 2010, is there a way for it to auto discover and realize the mailbox is on 2003 and auto configure for the 2003 user?

other wise, i have to have all 2003 exchange users that are running outlook 2010 clients to choose "manual" config when creating a new profile.

any advice would be appreciated!

Open an exchange powershell and run the following command;

get-set-OwaVirtualDirectory | set-OwaVirtualDirectory -Exchange2003Url https://FullUrlToYour Exchange2003Server

The owa connection has no need to be joined to the domain.  It is just a redirect for 2003 users. I do not get Akhaters comment at all.

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

@PeterSinger the OP never talked about OWA maybe you should re-read the question

HI Peter, i was referring to the MAPI clients connecting from outlook 2010, we already had the OWA redirect in place.
Akhater, when i test from a domain PC with a user account on Exchange 2003, i get this error code:
MIcrosoft outlook - an unknown error occurred, error code: 0x80070057
i then get the option to manual configure the profile.

the autodiscover / autoconfigure works fine for any exchange 2010 users, its only the legacy exchange 2003 that get the error.

Hi Akhater, yes i did see that hotfix however its not really an option as we have 5000+ users, 90% of which are still on 2003. deploying the hotfix on all users is not really an option.
i guess we'll have to tell them to manually configure any new profiles. was hoping there was a better way to approach it.

oh well it is a bug in outlook that was fixed by the hotfix but technically it does work as i previously said.

honestly deploying a hotfix is easier to manually configure 5k clients anyway it is your call
