After installing a new Exchange 2016 server into Existing Exchange 2010 environment I am getting errors related to OAB on the 2016 server.
Scenario: ProcessOrgExtensions. The organization mailbox for <domain> could not be retrieved.
Additionally, OAB is being generated and saved in C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\OAB but it does not appear in C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\oab
Any ideas are greatly appreciated.
