How to Delete an OAB

The Offline Address Book (OAB) stores all the properties of an Outlook user, like her name, email address, phone number and company alias. With OAB, Outlook does not have to be connected to the server to obtain a user's details. Instead, Outlook obtains such information from the local OAB. You can delete the OAB if you wish to restructure your company/organization directory. You will need administrative privileges to execute this task.

Things You'll Need

• Microsoft Exchange Server

Instructions

1. Click on "Start" and select "All Programs." Scroll up to find "Microsoft Exchange Server 2007." Click on it.

2. Click on "Exchange Management Shell." This will open a new window with a command prompt.

3. Type the following in the command prompt:

   Remove-OfflineAddressBook -Identity <OfflineAddressBookIdParameter>

   Replace "<OfflineAddressBookIdParameter>" with the name of your OAB. Contact your IT department or your Internet service provider if you are not sure of the name of your OAB.

4. Press "Y" to confirm the delete and press the "Enter" key to end task.
