Can't get OneDrive for Business and Exchange 2016 cu7 for Document Collaboration working

I have tried to follow this MS article, but ...

Our environment is:
ORF Spam Control (on Exchange Server)
DKIM Signature Signer (on Exchange Server)
Exchange 2016 cu7 Server (standalone 2012R2)
OOS (standalone 2012R2)
OneDrive (Cloud office365 account)

Use case scenario: to use Onedrive as a shared document repository for our exchange server where users via OWA or local outlook client can upload shared documents, end attachments and use OOS to view/edit said documents stored on OneDrive, effectively using OneDrive for document collaboration.

We do not want or wish to migrate our system to the cloud.

What has been done so far:

1) Setup office365 account and can access via
2) Setup Domain ''
- Added a .txt verification record to our zone file on our NS Servers.
-- made default, domain setup complete with no obvious errors.
3) Linked via Hybrid Configuration wizard (HCW) local exchange and our Office365 account
- used minimal setting as were not migrating our exchange to the cloud.
- all looks good HCW complete with no errors.
-- had one oddity, I could not log in to the admin account that had the admin credentials locally could use my e-mail account that does not have admin privileges, no idea why does not seem not to affect the outcome.
4) Added users in Office365 and allocated one drive licences accordingly.
- I assume this is required but unclear if that is the case.
5) Setup the following via the Exchange Management Shell on the local Exchange server.
[EMS] Set-OwaMailboxPolicy Default -InternalSPMySiteHostURL -ExternalSPMySiteHostURL
[EMS] Set-OwaMailboxPolicy Default -IsDefault
[EMS] Set-CASMailbox -OwaMailboxPolicy Default (did this as a test)
[EMS] Restart-WebAppPool MSExchangeOWAAppPool

Open in new window

Anyone got any ideas.

If you are in a hybrid configuration with Office 365 and your on-prem environment you should be creating users locally and syncing to Office 365 through an AD sync.  Can you verify your on-prem AD is synced with Office 365?

Hello Jason, I may have misunderstood, I am not looking to integrate with office365, according to the information requirement wise I have seen that all I need is a valid office 365 or one drive business to do this.

I have a valid VLK Exchange 2016 licence and One Drive (Business)

Seems I need to talk to someone that done this before, I no idea even how to go about finding someone for this.

Hi Jason, I thought the Hybrid Configuration Wizard, did that let me look at that again.
Peter AtkinAuthor Commented:
Hello, Jason, I can confirm that Active Directory synchronization was done and is complete, I really need to know what steps to take to complete this/or diagnose, to say this had been one of the worst integration experience I had in my 35+years as an IT thing is an understatement.

I feel your pain man.  In that case I would test authentication by logging into OneDrive on the web using domain creds for a licensed user.
Peter AtkinAuthor Commented:
Hi Jason, thanks :), everything works as expected other than onsite exchange not having the option to save or load attachments from one drive.

I even rerun the HCW from the server just in case and all green, no unexpecteds at all.

I can access my one drive accounts, I can see in office 365 all my AD accounts etc, sync is working I tested that, I have not peeked in Azure, but guess that must be fine as its linked to Office365, I'm stumped.
Peter AtkinAuthor Commented:
I feel confident in identifying the issue as: OAuth authentication not been setup correctly, now to work.
