Hi,
Outloo use MAPI protocol to communication with Exchange.
OAB is Offline Address Book that downloaded version of your Global Address
List etc... to local machine, allowing you to browse through company address
book while offline.
If you do use exchange server in your enviroment, it seem most likely that
your address book is missing. That why when you Send/Receive, an object can
not be found.
You can do a simple steps to see anything wrong with GAL by going to
Outlook, Tools, Send and Receive, download Offline address book.
If you're using a free email account (for example Hotmail), then you can try
to create a new profile by go to Control Panel, Mail, Show Profiles, Add
new profile. Change option to be prompted for which profile to be used. Open
Outlook again and choose that new profile, continue to set up your email
account.
Keep posting if you still have problem,
Tan,
