Hello,

Prompt update i abstracted Exchange from the mail001 loge. I then rebooted the D.C., and then booted letter box. Then it began working once more.

This is eminent in that it acts, yet i am a little implicated about transmigrating my 2003 host box mail host to Windows host 2008 just in case i get the same troubles again.

So not certainly if its 100% fixed i trust it doesn't get back. Otherwise you should updated your computer drivers. Once again you can do fresh set up of your operating system and then configure it. Hopeful that it not comes back again.

Thanks.

Hi,

The following scenarios might help you get started in fixing the error “The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action. ” This happens when the following scenarios are true:

You have a Microsoft Exchange Server 2007 server that is running the Client Access Server (CAS) role in the Exchange 2003 organization.

Either of the following registry values are set on the computer on which Outlook 2007 is installed:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Outlook\AutoDiscover

  • Value name: ZeroConfigExchange
  • Value type: REG_DWORD
  • Value data: 1

HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\AutoDiscover

  • Value name: ZeroConfigExchange
  • Value type: REG_DWORD
  • Value data: 1

Your mailbox is located on a mailbox server that is running Exchange Server 2003. You do not have an Outlook profile configured before you start Outlook 2007. There are 2 ways for you to follow in fixing the problem. You can use one of this in fixing the error.

The first way is to remove the ZeroConfigExchange registry data. You have to remove the Group Policy or the system policy that sets the following registry entry:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\AutoDiscover

  • Value name: ZeroConfigExchange
  • Value type: REG_DWORD
  • Value data: 1

Note: You may have to contact a domain administrator to modify this policy. You also have to delete the following non-policy registry data:

HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\AutoDiscover

  • Value name: ZeroConfigExchange
  • Value type: REG_DWORD
  • Value data: 1

The second way is to move the mailbox to an Exchange 2007 mailbox server however you don’t have to do this if the mailbox is located on an Exchange 2007 mailbox server.

Hope the information above was able to help you.

Thanks.
