Azure AD connect with existing O365 user accounts
Thanks, because its when I added my company.com domain to the existing company.onmicrosoft.com, the user's Outlook and O365 logins stopped working. That's where I'm stuck now.
I choose skip this and do this later because I wasn't sure what option to select, may be that's why.
That's right, adding the custom domain is the first of the pre-migration activities. You can take a look at the complete migration walkthrough.
- I only have about 100 mailboxes, so it looks like I can do cutover migration. I was already looking at CodeTwo for migration. But to before using CodeTwo, I have to first add my domain to Office 365 admin center right?
You don't have to use hybrid, here's an article on the possible migration scenarios.
Hi tantonyrei,
It depends of the number of mailboxes that you need to migrate and how will you plan it.
Find in the following link information about the different migration possibilities and their limitations:
