Federation with Office 365 is not configured


When Setting up Hybrid Mode the Hybrid Setup Wizard reports that “Federation with Office 365 is not configured”

Federation with Office 365 is not configured

Of course I have checked and double checked that the configuration has been done as expected. In fact I am able to see presence for users on O365 from other tenants.


I suspect the underlying cause has to do with the Blocked\Allowed Domains list for the On Premise deployment does not EXACTLY match that of yout online tenant



Honestly, this error can often be ignored and you will notice that if you simply click next that the reported issue is auto-magically resolved. That’s because the wizard actually tries to setup hybrid and resolve any issues.

That said, I have had to apply a “fix” at times

Simply remove (temporarily – so don’t panic) any entries you may have in the Allow or Block table in the Federated Domains tab.

Now run through the Hybrid Setup Wizard again and (in my case anyway) the error has disappeared.

SOLVED Federation with Office 365 is not configured

NOTE You may need to allow for a few minutes for the change to replicate before trying the Hybrid Setup Wizard again.

You can now re-add the Allow and Block entries in the SIP Federation Domains tab.


About Paul B

My name is Paul Bloem and I am employed at Lexel Systems in New Zealand as a Principal Consultant for Unified Communications. I have been working on enterprise voice solutions for over 20 years. My first 10 years were spent working for a Telco in South Africa (Telcom SA). This is where all the groundwork happened as I was exposed to just about every aspect of telecommunication you could imagine. I develop an interest in PBX technologies and eventually became the go-to guy. Next, I had a 10 year run at Siemens South Africa, most of my time there was as a Technical Trainer. During this time VoIP hit the world stage, I had the privilege of introducing VoIP both as H.323 and later SIP across the Siemens HiPath 4000 solution stack. In 2008 I immigrated to New Zealand with my newly attained MCSE, I was ready to go where no PBX Techie had gone before. I was employed to explore OCS 2007 and that was pretty much the beginning of the end for me. I have been working on OCS and Lync ever since. My current role focuses exclusively on Lync and associated technologies.. That includes pre-sales, consulting, architecture and design, training and support. I even get to play in the development space from time to time - focus on play ;-) I was nominated as a Microsoft VTSP for Lync early in 2013 and also awarded Microsoft's MVP award for Lync in 2014.
