I've been teaming with other folks in Office division to make the Office 365 Community as helpful as possible. A couple weeks ago, through a contact in the O365 community, I was told about a big collection of helpful technical videos, on the Office 365 channel, that the Office 365 team has released on YouTube. 

A few examples include Office 365 - Users Appear with O365 Domain After DirSync, "Unable to Connect" Error Message When Migrating Using the ECP, and Troubleshooting PowerShell for Exchange Online.
