outlook 2010 prompting for password after reconnect

Hello,

We have 2 Exchange servers:

Mail01 – Exchange server 2007 (old server)
Mail02 – Exchange server 2010 (new server)

The problem:
After installing the second server (Mail02) the users get in Outlook always a prompt that asks for their login information.
This only happens when they will reconnecting to the office network or when they start outlook before they do their network cable in the laptop.

It looks like it goes wrong when outlook would switch between HTTPS and RPC.

Thanks in advance for your help!

Hi Guys,

Thx for your answer.
We have found the problem:

After disabling Outlook Anywhere on both servers is the problem solved.  
Because our users have no access to email when they are out of Office. They can only use E-mail with a VPN connection or at the Office.

How far are you with the 2010 migration?

Do you have your certificate in place and your URLs configured on 2010? If not, I would do that and see if the problem goes away. It sounds like when they are coming into the local network it is picking up on 2010's autodiscover SCP.

This article discusses configuring namespace on 2010.

Please make sure your 2010 is the main CAS, you have installed your certificate and your DNS records have been updated to reflect you 2010 as the new main CAS.

If you have a user mailbox on 2010 and you try to access the mailbox using your 2007 CAS it will fail authentication.
Another possible reason will be your settings require "domain\username" combination.
