"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That is a pretty vague question.  

Where are the users migrated from?  

Assigned license for what?
Anthony K O365Author Commented:
Some Users mailbox data was migrated to Office 365. Some do not have a license assigned. I simply need a script to find those users and assign them license before the 30 day grace period.
Bob LearnedCommented:
I have zero experience with Office 365, but that doesn't mean that I can't help.  

I usually start by trying to find a good starting point.
