Hi I have 2 sites (from the AD perspective), office and DC. I have exchange 2010 installed at the OFFICE (ofexch1)location. i am in the process of moving exchange 2010 to the DC. So I have installed a new exchange 2010 in the dc (DCexh1). So I have setup owa and microsoft sync, they are hidden behind a NLB setup facing the internet. That is working okay. I have transport/mailbox /client access roles installed on both servers I have redirected the inboud to send first to dcexch1 all of that seems to be working. I have unmounted the MDB store in the ofexch1 server. but when I look at outlook and check my connection status i see 1) mail is still connecting to ofexch1 ( i presume its being proxied through to dcexch1) 2) my public folders is connected to the dcexch1 now why is it that my outlook is looking at ofexch1. Also I shut down ofexch1, thinking outlook would attach itself to dcexch1, but it just failed.... whats going on ? Alex I have migrated all the mailboxes over to the new MDB

Just to add to this I have tried to make some changes to the autodiscovery stuff # get current Site scope $sitescope= (Get-ClientAccessServer -Identity dcexh1).autodiscoversitescope Write-Host "Current Autodiscovery Site Scope : " $sitescope $sitescope += "YB" >>> this is the value in the ofexch box, but YB doesn't exist when i open sites / connectors only sites are dc and office #$sitescope = "dc" Set-ClientAccessServer DC1INTADCW8201 -AutoDiscoverSiteScope $sitescope $sitescope= (Get-ClientAccessServer -Identity dcexh1).autodiscoversitescope Write-Host "Updated Autodiscovery Site Scope : " $sitescope Still no joy so I am sitting in office with outlook, trying to point it to use the exchange server in dc and I can't seem to. My mailbox is in DC .... Can I unregister CAS in the office, will the dc on take over ?????? Alex

Hi Alex, From my perspective, you can try to rebuild a new Outlook profile which is point to old server. Give it a shot and feedback. Thanks.Rowen TechNet Community Support
