Why Exchange Server is Unavailable in Outlook 2007/2010

This problem could be occurred if you client computer doesn’t have the configuration of a default gateway. You have to add the DWORD value in the DEfConnectOpts registry.

In Outlook 10:

1. Start-Run-Type regedit and press Enter.
2. Locate the following key and click the subkey:

HKEY_CURRENT_USERSoftwareMicrosoftOffice14.0OutlookRPC

1. Select New from the edit Menu and click DWORD value.
2. Then Type DefConnectOpts and press Enter.
3. Right click DefConnectOpts and click Modify.
4. Type 0 in the value data box and click OK.
5. Exit Registry Editor.
