When creating mailboxes in new OU, the error "The Exchange server address list service failed to respond" is seen. Creating new mailboxes for already existing OU works fine. Problem since V2V migration (from hyper v to esxi).

Offline Address book definition is missing The 'msExchUseOAB' value for mailbox store 'Mailbox Database' on server VM02 is missing. This will cause offline address book errors for 3 users in this database.

OALGen skipped some entries in the offline address list '\Global Address List'. To see which entries are affected, event logging for the OAL Generator must be set to at least medium. - PAAB Offline Address Book9408
OALGen failed to load the offline address book version 4 manifest file '\VM02\ExchangeOAB\9227b150-e6b2-4cae-ade1-2df2d81e9b67\oab.xml'. This indicates data tampering or disk problems.

For the other ones: force a full Offline Address Book rebuild using
