Exchange 2016 Hybrid Offline Address Book
Hi all
Hope everyone is well. I was wondering something. Currently I have an Exchange 2016 Hybrid with all my mailboxes in Office 365. Is the OAB for the on-premise Exchange environment still being used or does Office 365 have it's own OAB? In Outlook even thou my mailbox is on Office 365 I can still see the OAB that we were using when our mailboxes were on-premise. Just curious
Hi, in Exchange Hybrid, any migrated mailboxes are going to obtain the OAB from Office 365 as opposed to Exchange on-premises.

Hi PeterRising
Thank you for your reply. How does one manage the OAB in Office 365? Is it something that we can manage? Also for Exchange 2016 on-premise it seems that it's not possible to manage the OAB via the EAC. Must it be done via powershell only?
Thanks again.
Hi, take a look at https://docs.microsoft.com/en-us/exchange/address-books/offline-address-books/offline-address-book-procedures
PowerShell is the way to manage these though yes.
