Missing Offline Address Book Feature

Latest update of eM Client version 8.2.1237 does not show the Offline Address Book feature.
Using an Exchange 2016 account.
Initial set up last year had Offline Address Book feature but after the update it’s just missing.
OAB is already enabled in Exchange server and able to view it on OWA.
If i go to Menu > Accounts, the only available tabs are General, Exchange Web Services, Diagnostics.
There used to be a Offline Address Book tab but now it doesn’t show at all.
Affecting many users.
