Office 365 & Microsoft Account directory merge

Question

The Azure account is managed and run by a Microsoft Account user. The same user has a Office 365 subscription so it has an work/organization account as well. Because the Microsoft sign-in pages are confused and messed up if a user needs to use different
accounts for different services (for example, when the user tries to go to portal.azure.com, it is sometimes automatically logged in using the Office 365 account which naturally does not work in Azure), we are thinking of merging these two directories
under one account. Based on the following articles it should be possible:
https://msdn.microsoft.com/en-us/library/azure/dn629581.aspx
https://msdn.microsoft.com/en-us/library/azure/dn629580.aspx
However, some crucial information are missing:
It is possible to rollback the merge (decouple/untrust the two directories) later on? How?
Based on
http://blogs.windows.com/business/2014/11/07/windows-10-manageability-choices/ the Windows 10 will (finally) support Azure AD accounts. Will it work flawlessly or this merge will make some issues (currently, we are using Microsoft Account to sign-in
to Windows 8.1) or lost functionality (for example, user will need to choose whether to log-in with Microsoft Account and live without Azure AD dependent functionality like auto-login to Office 365 apps/services or vice versa)?
Are there anything else we should be aware of?

Hi,
Thanks for your post.
It is possible to integrate Windows Azure account with an Office 365 account and here are the steps you must follow: 
Logon to the Windows Azure Portal
https://manage.windowsazure.com.
Click on Application Services | Active Directory | Directory | Custom Create.
Change the Directory dropdown from the default
Create new directory to Use existing directory
and click the Check box.
Next you are logged out of the Windows Azure administrative account and you are redirected to the Windows Azure Active Directory logon.
Logon with a Global Administrator account from the Office 365 tenant that you would like to integrate.
After sign in you are prompted to add the Windows Azure administrator account as a global administrator for the Office 365 Tenant directory, click on
Continue.
Logout of the Office 365 global administrator account and then logon to
https://manage.windowsazure.com with your global administrator account.
I did not find any MS article about rollback the merge.
For the Account related issue, i think you may ask Azure support:
