Unable to remove domain from Office 365. Please help!

In the middle of an Office 365 to Office 365 migration. Client has lots of domains and I have moved most of them. Last (and of course, main!) domain still in the old Tenant. Last two domains:

3.JPGDoing a little digging I have found one item which seems to be some kind of external user who some has shared content with:

I cannot seem to remove this item

Any ideas?

This is holding up the whole migration!!

Thanks

Apart from email aliases, you need to also check UPNs, SIP addresses, other services. There's a script that can help you with that on TechNet: https://gallery.technet.microsoft.com:443/How-to-remove-a-custom-6fe91693

Oh, and to remove the external user, use Remove-MsolUser, then remove him from the recycle bin as well. You can check all of them via:

Get-MsolUser | ? {$_.UserType -eq "Guest"}

Hi Vasil

I was able to remove other domains where accounts held @domain as secondary email addresses so im 99% convinced that its this odd external user.

Running the Get-MsolUser | ? {$_.UserType -eq "Guest"} I get:
Get-MsolUser : An error occurred during authentication. Please retry your operation. If this problem persists, contact Technical Support.

The error message above is connectivity issue, not related to the cmdlet.

In any case, run the script or do a simple

Get-MsolUser -DomainName domain.com

Open in new window


to find any remaining objects.
