Change the offline address book generation schedule
An offline address book (OAB) is a copy of an address book that's been downloaded so that an Outlook user can access the information it contains while disconnected from the server. You can configure how often the OAB is generated by using the OABGeneratorWorkCycle and OABGeneratorWorkCycleCheckpoint parameters on the Set-MailboxServer cmdlet.
For additional management tasks related to OABs, see Offline address book procedures.
What do you need to know before you begin?
Estimated time to complete each procedure: 5 minutes.
