How to view your "Cloud Only" users in Azure AD Powershell

I ran into an issue recently with a customer who had populated their cloud with users manually, and then ran DirSync to synchronize 1000s of user accounts.   We then had a need to audit the cloud only accounts and come up with a plan to remove them.   I found this to be a very effective way to address this.

Get-MsolUser -All | where { $_.ImmutableId -eq $null }

The ImmutableId field is created when users are synchronized from an external directory, so users without a ImmutableId are not from Active Directory.

Microsoft Lync TRIPP reports have been replaced

I use the Lync TRIPP reports often.  Despite many people clamoring that it uses Java or works incorrectly, I have found them to be pretty handy to ensure a customer's network is sufficient to support audio/video calling for both Lync Online as well as On premise.

None of the links in that article work anymore, however (thanks to Henrik Walther) there are new links available here:

Most excellent.  Wish they'd make the old URL's redirect or something, since there are so many blogs that point to them now.
