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).
- Date and time is correct on exchange + the ad servers
- Test-ServiceHelath shows all services running

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.

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