exchange 2010 autodiscover issue
Posted on 2012-12-26
We are in the middle of migrating on of our customers from an Exchange 2003 to an Exchange 2010 server.
This customer has a very particular situation to which i haven't found a solution yet.
Let me first explain the current situation.
This company has an exchange server situated in the UK and an Exchange environment in Belgium.
The primary exchange environment is the UK one, so ALL incoming emails are sent to an MX-record pointing to the UK server. To get the emails from Users that are in Belgium, on their exchange environment, there is a pop3 download engine that pulls all mails from their accounts in UK and putts them into their own exchange environment. Primary SMTP address is identical for BOTH the UK en Belgian environment (let me call this domain name: mail.com).
This situation has been working fine, as both sides were running an exchange 2003 environment that did NOT support autodisover records.
When we started the migration to Exchange 2010, upon connection of the first mailbox, we came up with the following issue. Outlook perfectly connects to the new Exchange2010 server, but keeps prompting for the autodiscover record.
The autodiscover record that is requested is autodiscover.mail.com, so in fact, this points to their UK server, as that domain name primarily is configured on the UK server.
Now is my question:
How do i get the client pc's to connect to the actual rpc over http address (for the Belgian organisation) in stead of going to the UK side?
Additional, but very important information:
We do NOT manage the UK server side, only the Belgian server side.....
Hope I've clearly stated my problem and hope to see a solution to my issue soon.
