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