Exchange 2016 oab not updating outlook 2016
Here, I will create an offline address book called Ottawa-OAB and include Ottawa-Address-List address list.Then I will assign this address book to mailbox users who live in Ottawa city.
It is the OABGen service that identifies the recipients that should be member of offline address book.
This article will introduce the solution to deal with this issue.
Change update interval/frequency for Offline Address Book (GAL) in Outlook To change the update frequency for offline global address book in Outlook, you need to define an individual send/receive group, and configure the update interval for this group.
As you can see above, the name of OAB is Default Offline Address Book and it has the Default Global Address List.
This means that all the recipients are member of Default OAB.
