Unable to Activate DirSync

I came across a unique incident today while working in an Office 365 tenant.  After getting things ready for Directory Synchronization internally and on the tenant side, the time had come to Turn on DirSync within the O365 Portal. I had downloaded the Azure Active Directory Synchronization install (DirSync), created the accounts needed for the install and was ready to go.  Within the Portal, after clicking on Users/Active Users then selecting Active Directory Synchronization Set up, under Step #3 Activate Active Directory Synchronization I clicked Activate

This returned an error that it couldn’t be completed;

Sorry, we can’t process your request.

we’re investigating right now. Please try again later.

After waiting awhile, this did not ‘resolve itself’ and a support ticket was opened. After escalation and still no results, i found a good article (http://blogs.perficient.com/microsoft/2015/04/office-365-unable-to-activate-directory-synchronization/) explaining the same problem -and a solution!

Logging into the portal through PowerShell and running a Get-MsolDomain, i saw that the tenant.mail.onmicrosoft.com domain was indeed in there.

I ran Remove-MsolDomain tenant.mail.onmicrosoft.com and verified it was gone, then went back and tried the Activate button again (in Step #3) -It works!

If anyone runs into this problem, I hope that if they haven’t come across the Perficient blog they see this one and are able to fix the issue quickly.
