Exchange – Offline Address Book

How to update and deliver the OAB (Offline Address Book):

The OAB is basically updated (generated) automatically, but we are able to force this process:

  • Get-OfflineAddressBook | Update-OfflineAddressBook

We need to deliver updated OAB to CAS server(s) for our clients:

  • Get-ClientAccessServer | Update-FileDistributionService

Outlook clients can download updated OAB:

  1. On the Tools menu, point to Send/Receive, and then click Download Address Book.
  2. Under Information to download, click Full Details or No Details.
