Outlook 2010 only to show address book from one email account

When multiple accounts are added on Outlook 2010 and you create a new email, autocomplete in the 'to' field shows suggestions from every account. Is it possible to only show suggestions relevant to the account the email is being sent from.

For example, if I had my personal account and a customer services account, when I go to send an email from my personal account, every email address who has ever communicated with the customer services account shows which is quite risky.

Thanks, Louise

Have you looked in the help section of outlook. The only thing i can suggest at the moment, is click the contacts in outlook,and then the little arrow next my contacts, there you will find yor email accounts with suggested contacts and contacts, see what happens when you try that.
