Outlook prompt with (Exchange Server) Windows everytime a start it

Hello @all,

I have a strange thing after my changes on my Exchange Server boxes.

Bachground:
My Certificate was going to expire and i would renew the cert. I thing this is a good time to fix some names in the certificate to make the live easy with short names (the old public name was very long).

I have two exchange servers 2010 SP2 UR5 with one dag and each server has one db in the dag for replicating.

--------
Changes on the Exchange Environment:

So I generate the new certificate an send it to to the public ca. After I receive the certificate I finish the cert-request on the exchange environment.

1. I change the ClientAccessArray fqdn to the new value
2. I change the Mmailbox db's and public folder db's to the new name
3. I change all the InternalURL's and ExternalURL's (OwaVirtualDirectory, EcpVirtualDirectory, OabVirtualDirectory, WebServicesVirtualDirectory, AutodiscoverVirtualDirectory, ActiveSyncVirtualDirectory) and the Outlook Anywhere hostname
4. I set the spn's to the new values

setspn -S http/server.domain.tld server$
setspn -S exchangeRFR/server.domain.tld server$
setspn -S exchangeAB/server.domain.tld server$
setspn -S exchangeMDB/server.domain.tld server$

5. and I start RollAlternateServiceAccountPassword.ps1

So after that all my internal clients will work normally. But my external Outlook 2010 clients will open every start the Windows "Exchange Server" to veryfy my account details.

Does anyone know something abaut that?
