One day I needed to implement identity synchronization and federation. So, I installed dirsync, plus ADFS. All worked fine and as expected.
I deleted all those instances, the Domain Contoller, the Exchange Mailbox Role and the ADFS.
What I never did was convert back the <a target="_blank" href="http://allthingscloud.info"><a href="http://allthingscloud.info" class="autolinkedURL autolinkedURL-url" target="_blank">allthingscloud.info</a></a> domain from Federated to Managed in 365.
I thought it was going to be much more complex considering the ADFS doesn't exist anymore, but no.

One day I needed to implement identity synchronization and federation. So, I installed  dirsync, plus ADFS. All worked fine and as expected.

I deleted all those instances, the Domain Contoller, the Exchange Mailbox Role and the ADFS.

What I never did was convert back the [***allthingscloud.info***](http://allthingscloud.info) domain from Federated to Managed in 365.

I thought it was going to be much more complex considering the ADFS doesn't exist anymore, but no.

Converting an Office 365 Domain from Federated to Managed

I write in TL;DR what I come across in my work as Cloud Architect. I use this as a notepad of the things I do to get back to them when I need them.
