Periodically people have to setup their email accounts again, either because they get a new computer or have to reinstall software. Sometimes it is just an update installed on an exchange server. Either way sometimes some settings may need to be reset.
One of the most common questions we get is, "Where did my address book go? ". Usually people can see their contacts, but with an exchange server sometimes the default address book when you click "To" shows no contacts. By default the Exchange Global Address Book is the first source of contacts.
In order to resolve this you just need to change the default address book in Outlook 2010.
- In Outlook 2010, Select Contacts in the navigation pane
2. Select Address Book from the ribbon menu
3. The Address Book window opens
4. Select the Tools Menu
5. Select Options
6. Choose Start with contact folders
7. Click OK
From now on when you click the "To" button your default address list will be the outlook contacts folder.
