I have a 64-bit Win 7 computer that has connected to a SBS2003 domain via the connectcomputer wizard. Outlook 2007 has been configured with an Exchange account and a POP account. I need the POP account to remain as the default account, however, when I reboot or logoff/logon, the Exchange account is reconfigured as the default mail account. The simple solution for Outllok running on WinXP computers - changing the NoTransportOrder registry setting - does not work in Windows7 since the registry key does not exist (and creating the keys and DWORD does not help). Renaming the sbsdefault.prf file on the SBS 2003 server did not help, and changing the computer settings in the server managment console to not change the Outlook profile also did not help. Any ideas?
