How to enable Outlook Anywhere from Exchange 2003

Quick background:  I'm trying to migrate mailboxes from Exchange 2003 to Exchange Online. Accroding to this article (https://support.office.com/en-gb/article/Perform-a-staged-migration-of-email-to-Office-365-83bc0b69-de47-4cc4-a57d-47e478e4894e?ui=en-US&rs=en-GB&ad=GB#PrepareforCutover) I need to enable Outlook anywhere/RPC over HTTP. That links to another article (https://technet.microsoft.com/library/aa996922(EXCHG.80).aspx) which says I need to:

  • Install CA SSL certificate (done)
  • Enabled the RPC over HTTP proxy component in Windows (done, and rebooted)
  • Run the Enable Outlook Anywhere Wizard on at least one Client Access server in your Exchange deployment.

It's this 3rd item I can't work out how to do, and I've scoured the Internet and get no useful leads. I can see articles which show how to Enable Outlook Anywhere in Exchange 2007, but not 2003, as there is no Client Access Server area that I can see.

Anyone know how to do this please?

to enable Outlook Anywhere (RPC over HTTPS, as it was called in Exchange 2003) you can follow this guide:

I haven't tried to do migration from 2003 to Office 365, but this guide is for enabling that functionality.

Hi Ivan,

I've been following that guide already, but it doesn't create a virtual directory in IIS after I install the RPC component - I have a separate issue open for that actually: https://www.experts-exchange.com/questions/28977125/Setting-up-RPC-over-HTTP-on-Exchange-2003.html

But that article doesn't mention how to "Run the Enable Outlook Anywhere Wizard" in Exchange 2003 (as per https://technet.microsoft.com/library/aa996922(EXCHG.80).aspx) which it what I' trying to find out. I'm really starting to think there is no option to do this!

If the RPC virtual directory isn't there, you probably have more issues with that server than are worth exploring.  The RPC v-dir should be there even before you enable 'RPC over HTTP Proxy'.

I am certain you are migrating to Exchange Online it is because you are well aware Exchange 2003 is no longer supported--which means Exchange 2003 isn't supported for staged migrations either.

Have you considered moving to Exchange 2007 and then migrating to Exchange Online?
IvanSystem EngineerCommented:

that guide (https://technet.microsoft.com/library/aa996922(EXCHG.80).aspx) is for enabling Outlook Anywhere for Exchange deployment that have Exchange 2007 and Exchange 2003.
Not for Exchange organization that have just Exchange 2003. :)

As per article, you should have Exchange 2007 CAS server, on which you would enable Outlook Anywhere, and that 2007 CAS server would automatically manage access to that 2003/ 2007 machine.

PS: Maybe you cant use this type of migration without min 1 CAS 2007 server.

I tried to make identical migration from 2003 to Exchange Online, but it does not work.
I migrated e-mails to PST and later migrated to Mailbox Online.
