I have simulation related to the Microsoft Exchange 2007 and Microsoft Outlook client (Office 2007) in the enterprise environment.
If the client machines (with the XP operating system), everything is OK
- The client machines (with XP operating system) at LAN 1 (192.168.51.0/24) can connect or enable the email, either with “Outlook Client” (Office 2007) or “OWA (outlook web access”; the emails work very well
- The client machines (with XP operating system) at LAN 2 (192.168.52.0/24) can connect or enable the email, either with “Outlook Client” (Office 2007) or “OWA” (outlook web access); the emails work very well
But If the client machines use the Windows 7, I have the problems with “Outlook Client” (I can not ENABLE it at all); the error message are as the followings: “ Outlook cannot log on. Verify you are connected to the network and are using the proper server and mailbox name. The Connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action”
However, If I execute “Outlook Web Access” (OWA) at the same Windows 7 above, the users are able to send or receive the emails (and other things) well.
So, This seems the problem of Microsoft Outlook Client (Office 2007) at Windows 7 [Because if I use the same Outlook Client (office 2007) at Windows XP, everything work well]
