In my case the reason was missing objectSID which is mandatory to create linked mailbox. This caused the CreateMailbox command to fail with the same error code as you had (which is not very informative). The partially failed seems to create AD accounts with some of the Exchange attributes in place. Eg email attributes are set but mailbox is not created. Exchange thinks that these objects are contacts. Contacts require the ExternalEmailAddress to be set and that is the cause for misleading error message. After adding few lines of code to check that all mandatory attributes are present provisioning worked fine.
