HCW8104 - The tenant Federated Organization Identifier is corrupt. No Delegation Trust Link.

I had this question after viewing Exchange 2013 Hybrid setup - HCW0 No federation trust is configured for this organization.

We have had an Office 365 tenant for years now, but have never migrated to it. Now that we wish to do so, I am getting the error in the subject line. Microsoft has worked on our inability to create a hybrid config off and on for the past year or more, with ZERO progress.

I see that one solution is to create a new tenant...does that mean creating an entirely new Office 365 account setup for our entire K-12 school district?  It's hard to imagine that switching to an entirely new Office 365 tenant domain name would not be a huge headache!

Perhaps I just don't understand the process. It was mentioned in the solution article listed above.

HELP!

Never seen this error, make sure to report it/submit feedback via the HCW. Out of curiosity, what does Get-FederatedOrganizationIdentifier return? I guess you can simply try to recreate it manually as detailed here: https://technet.microsoft.com/en-us/library/jj657462%28v=exchg.160%29.aspx

If support is giving you trouble, ask to get the issue escalated.

The Get-FederatedOrganizationIdentifier gave no errors, but has the following:

ExchangeVersion:  0.10 (14.0.100.0)
IsValid:                     True
WhenChanged:     8/15/2017
WhenCreated:      11/12/2010
It seems a bit old, maybe they've introduced some changes since that are causing the issue? Try recreating it.
How can I recreate it without deleting or breaking what is already in place?
Well that's the idea - remove what's already there as it does seem broken. The steps to create new trust are listed in the article I linked above.
So, if we are talking about creating a new tenant, does that mean I need to register a new domain name and everything?

Registering a new tenant will take you a lot more compared to simply trying to recreate the trust.
I have deleted and recreated the federation trust a couple of times, making sure to also change the DNS TXT records to match the new proof IDs.  Creating the Federation Trust works (Microsoft Federation Gateway), adding the domains to the Federation Trust works, creating the Organizational Relationship does NOT work, and the Hybrid Config Wizard does NOT complete, and gives the message in the subject of this question.

Thanks for that info Vasil.  However, once I have used the wizard the first time and chosen the full hybrid configuration, I no longer have the option to select Minimal.  I'm trying to research if it's possible to get that option back.  Any idea if that's possible?

I guess it detects some setting on the tenant or the Hybrid object on-premises and thus doesnt allow you to use the minimal Hybrid option. You should definitely check with support, and have them escalate this.

Other than that, you can certainly use other migration methods, but they lack the end user experience offered by Hybrid.
Well, we settled on using the Minimal Hybrid configuration, as that would allow the HCW to complete.  Thanks for your help!
