Exchange Online vs. on-premises functionality

I'm the admin of an on-premises Exchange Server.  In addition to user mailboxes, I have over 1000 contacts and lots of distribution groups, consisting of user mailboxes and contact email addresses.  And I set up for forwarding of incoming user emails to outside addresses, sometimes also delivering to user inboxes and sometimes not.  I have full admin rights to users mailboxes. I can hide addresses from the Global Address List.   Question:  Can I do all of these things in Exchange Online?  Related question (or maybe the same rephrased):  Can I manage the Global Address List from anywhere and to the same extent I now can?

Yes you will be able to do all the above. Somethings you will need powershell, like setting an option for a user for their password not expire.

You might want to take a look at the different plans for the users though, that is something to keep in mind because they all come with different things.

Well, that is good news.  I'm perpetually uneasy about the whole on-premises scenario.  I'd love to hand off responsibility for 99.99% uptime to someone.  

Is there anything you can tell me about migrating my current GAL to Outlook Online?

Oops.  I meant Exchange Online, not Outlook Online.

yeah lol! the good news is that when people use office 365 at least now a days they have small issues, the migration part depends on exchange if you're using 2010 or 2013 also there's something called hybrid migration that you can have them both and do mail flow from the premise and have the mail boxes in the cloud

and then switch over when every one is ready.

I put in a bunch of links depending on how big everyone's mail box is - I would make sure you have full back ups of the whole server before even going at it.

The time it takes depends on the number of users and how big your team is, powershell brings down the time a lot.
