Looking at doing an Exchange 2010 to O365 cutover migration in a few weeks and wanted to make sure I can use AADConnect/DirSync AFTER the migration is done/licenses applied/etc. It is ~50 users and not a lot of mailbox items.
The plan is to do the following:
Do I have that correct? My LAST step should be to set up AADConnect/DirSync? If so, anything I need to be aware of? Just make sure the SMTP attribute in AD matches what is in O365? Is anything going to happen after I remove Exchange?

You can do that, but you will not have support from Microsoft because you need to maintain the Exchange, if you uninstall your Exchange you cannot have AD Connect fully supported.

You will need to install a new Exchange Hybrid a Hybrid License, you can read more here https://support.microsoft.com/en-us/help/2939261/how-to-obtain-an-exchange-hybrid-edition-product-ke...

We currently have AD Sync running inside our network with no Exchange Server locally. We don't have any problems however its a pain when we need to make user changes as we need to use the attribute editor in AD, can be a pain.
We did not want a local Exchange Server as the end goal was to migrate to 365 removing the local hassle of managing a local Exchange box. which has been done.
Without installing a local exchange server is there anything else we can install / do to help managing users (without using Attribute editor?)

You will need Exchange Hybrid to have full support from Microsoft, and depending your license you do not pay Exchange Server, you can view and request the key here http://aka.ms/hybridkey

Hey @Mark Valpreda
How was finally you did the setup? i´m about to do the same cutover migrtion, and i have the same doubt about when deploy AAD Connect and if going to have problems with that.
I hope you can answer my concern
